This book documents commands used to configure Voice over ATM, Voice over Frame Relay, Voice over HDLC, Voice over IP, video, head-end universal broadband features, and subscriber-end universal broadband features. Commands in this book are listed alphabetically. For information on how to configure Voice over ATM, Voice over Frame Relay, Voice over HDLC, Voice over IP, video, head-end universal broadband features, and subscriber-end universal broadband features, refer to the Cisco IOS Multiservice Applications Configuration Guide.
For FXO and FXS voice ports:
signal {loop-start | ground-start}
no signal {loop-start | ground-start}
For E&M voice ports:
signal {wink-start | immediate | delay-dial}
no signal {wink-start | immediate | delay-dial}
Syntax Description
loop-start Specifies loop start signalling. Used for FXO and FXS interfaces. With loop start signalling only one side of a connection can hang up. This is the default setting for FXO and FXS voice ports. ground-start Specifies ground start signalling. Used for FXO and FXS interfaces. Ground Start allows both sides of a connection to place a call and to hang up. wink-start Indicates that the calling side seizes the line by going off-hook on its E-lead then waits for a short off-hook "wink" indication on its M lead from the called side before sending address information as DTMF digits. Used for E&M tie trunk interfaces. This is the default setting for E&M voice ports. immediate Indicates that the calling side seizes the line by going off-hook on its E-lead and sends address information as DTMF digits. Used for E&M tie trunk interfaces. delay-dial Indicates that the calling side seizes the line by going off-hook on its E-lead. After a timing interval, the calling side looks at the supervision from the called side. If the supervision is on-hook, the calling side starts sending information as DTMF digits; otherwise, the calling side waits until the called side goes on-hook and then starts sending address information. Used for E&M tie trunk interfaces.
Defaults
loop-start for FXO and FXS interfaces; wink-start for E&M interfaces

Usage Guidelines
This command applies to analog voice ports only.
Configuring the signal command for an FXS or FXO voice port changes the signal value for both voice ports on a VPM card.
 |
Note If you change the signal type for an FXO voice port on Cisco 3600 series routers, you need to move the appropriate jumper in the voice interface card of the voice network module. For more information about the physical characteristics of the voice network module, refer to the installation documentation, Voice Network Module and Voice Interface Card Configuration Note, that came with your voice network module. |
Configuring this command for an E&M voice port changes only the signal value for the selected voice port. In either case, the voice port must be shut down and then activated before the configured values will take effect.
Some PBXs will miss initial digits if the E&M voice port is configured for Immediate signalling. If this occurs, use Delay-Dial signalling instead. Some non-Cisco devices have a limited number of DTMF receivers. This type of equipment must delay the calling side until a DTMF receiver is available.
Examples
The following example configures ground start signalling on the Cisco 3600 series, which means that both sides of a connection can place a call and hang up, as the signalling type for a voice port:
configure terminal voice-port 1/1/1 signal ground-start

Usage Guidelines
Before configuring the signalling pattern, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. The voice class must then be assigned to a dial peer.
This command must be entered twice. When you enter the command to specify the signalling pattern for the idle transmit state, you must reenter the command to specify the signalling pattern for the idle receive state.
The idle state of a call is normally based on both the transmit and receive idle patterns matching the signalling state in the signalling packets. If only one direction is configured (transmit or receive), the idle state will be detected based only on the direction that is configured. The out-of-service (OOS) transmit pattern is matched against the signalling state from the PBX (and transmitted to the network). This is used in conjunction with either the suppress-voice timing parameter or the suppress-all parameter.
The OOS receive pattern is the pattern sent to the PBX if the signal timing oos timeout timer expires during which no signalling packets are received from the network. The OOS receive pattern is not used for pattern matching against the signalling packets received from the network. The receive packets directly indicate an OOS condition by setting the AIS alarm indication bit in the packet.
To "busy out" a PBX if the network connection fails, set the OOS receive pattern to match the seized state (busy), then set the signal timing oos timeout value. When the timeout value expires and no signalling packets have been received, the router will send the OOS receive pattern to the PBX.
Use the busy seized pattern only if the PBX does not have a special pattern specifically intended to indicate an OOS state. If the PBX does have a specific OOS pattern, use that pattern instead.
Examples
The following example, beginning in global configuration mode, configures the signalling bit pattern for the idle receive and transmit states:
voice class permanent 10
signal keepalive 3
signal pattern idle receive 0101
signal pattern idle transmit 0101
exit dial-peer voice 100 vofr voice-class permanent 10
The following example, beginning in global configuration mode, configures the signalling bit pattern for the out-of-service receive and transmit states:
voice class permanent 10
signal keepalive 3
signal pattern oos receive 0001
signal pattern oos transmit 0001 exit dial-peer voice 100 vofr voice-class permanent 10

Usage Guidelines
Before configuring the signal timing idle suppress-voice timer, you must use the voice class permanent command in global configuration mode to create a voice class for the Cisco trunk or FRF.11 trunk. The voice class must then be assigned to a dial peer.
This command is used when the signal-type command is set to transparent in the dial peer for the Cisco trunk or FRF.11 trunk connection. The Cisco MC3810 stops sending voice packets when the timer expires. Signalling packets are still sent.
Examples
The following example, beginning in global configuration mode, sets the signal timing idle suppress-voice timer to 5 for the idle state on voice class "10."

no signal-type {cas | cept | ext-signal | transparent}
Syntax Description
cas North American EIA-464 channel-associated signalling (robbed-bit signalling). cept Provides a basic E1 ABCD signalling protocol. Used primarily for E&M interfaces. When used with FXS/FXO interfaces, this protocol is equivalent to MELCAS. ext-signal External signalling. The digital signal processor (DSP) does not generate any signalling frames. Use this option when there is an external signalling channel (for example, CCS) or when you need to have a permanent "dumb" voice pipe. transparent Selecting this option produces different results depending on whether you are using a digital voice module (DVM) or an analog voice module (AVM). For a DVM: The ABCD signalling bits are copied from or transported through the T1/E1 interface "transparently," without modification or interpretation. This enables the MC3810 to handle arbitrary or unknown signalling protocols. For an AVM: It is not possible to provide "transparent" behavior because the Cisco MC3810 must interpret the signalling information in order to read/write the correct state to the analog hardware. This option is mapped to be equal to "cas."

Usage Guidelines
This command applies to VoFR, VoATM, and VoHDLC dial peers. It is used with permanent connections only (Cisco trunks and FRF.11 trunks), not with switched calls.
This command is used to inform the local telephony interface of the type of signalling it should expect to receive from the far-end dial peer. To turn signalling off at this dial peer, select the ext-signal option. If signalling is turned off and there are no external signalling channels, a "hot" line exists, enabling this dial peer to connect to anything at the far end.
On the Cisco 2600 series and 3600 series routers, there are only two possible settings for trunks (VoFR dial peers only):
When you connect an FXS to another FXS, or if you have anything other than an FXS/FXO or E&M/E&M pair, the appropriate signalling type on Cisco 2600 series and 3600 series routers is ext-signal (disabled).
On the Cisco MC3810, there are two additional signal-type settings:
If you have a digital E1 connection at the remote end that is running cept/MELCAS signalling and you then trunk that across to an analog port, you should make sure that you configure both ends for the cept signal-type.
If you have a T1 or E1 connection at both ends and the T1/E1 is running a signalling protocol that is neither EIA-464nor cept/MELCAS, you might want to configure the signal-type for the transparent option in order to pass through the signalling.
Examples
The following example shows how to disable signalling on a Cisco 2600 series or 3600 series router or on a Cisco MC3810 multiservice access concentrator for VoFR dial peer 200, starting from global configuration mode:
dial-peer voice 200 vofr signal-type ext-signal

Usage Guidelines
This command indicates whether or not supervisory disconnect signalling is available on the FXO port. Supervisory disconnect signalling is a power denial from the switch lasting at least 350 milliseconds. When this condition is detected, the system interprets this as a disconnect indication from the switch and clears the call.
You should configure no supervisory disconnect on the voice port if there is no supervisory disconnect available from the switch.
|
Note If there is no disconnect supervision on the voice port, the interface could be left active if the caller abandons the call before the far end answers. After the router collects the dialed digits but before the called party answers, the router starts a tone detector. Within this time window, the tone detector listens for signals (such as a fast busy signal) that occur if the originating caller hangs up. If this occurs, the router will interpret those tones as a disconnect indication and close the window. |
Examples
The following example configures supervisory disconnect on a Cisco 3600 series voice port:
voice-port 2/1/0 supervisory disconnect
The following example configures supervisory disconnect on a Cisco MC3810 voice-port:

Syntax Description
number Defines the numbers used as the technology prefix. Each technology prefix can contain up to 11 characters. Although not strictly necessary, a pound (#) symbol is frequently used as the last digit in a technology prefix. Valid characters are 0 though 9, the pound (#) symbol, and the asterisk (*).
Defaults

Command History
11.3(6)NA2 This command was introduced.
Release
Modification
Usage Guidelines
Technology prefixes are used to distinguish between gateways having specific capabilities within a given zone. In the exchange between the gateway and the gatekeeper, the technology prefix is used to select a gateway after the zone has been selected. Use the tech-prefix command to define technology prefixes.
Technology prefixes can be used as a discriminator so that the gateway can tell the gatekeeper that a certain technology is associated with a particular call (for example, 15# could mean a fax transmission), or it can be used like an area code for more generic routing. No standard defines what the numbers in a technology prefix mean; by convention, technology prefixes are designated by a pound (#) symbol as the last character.
In most cases, there is a dynamic protocol exchange between the gateway and the gatekeeper that enables the gateway to inform the gatekeeper about technology prefixes and where to forward calls. If, for some reason, that dynamic registry feature is not in effect, you can statically configure the gatekeeper to query the gateway for this information by configuring the gw-type-prefix command on the gatekeeper. Use the show gatekeeper gw-type-prefix to display how the gatekeeper has mapped the technology prefixes to local gateways.
|
Note Cisco gatekeepers use the asterisk (*) as a reserved character. If you are using Cisco gatekeepers, do not use the asterisk as part of the technology prefix. |
Examples
The following example defines a technology prefix of 14# for the specified dial peer. In this example, the technology prefix means that the H.323 gateway will ask the RAS gatekeeper to direct calls using the technology prefix of 14#.
dial-peer voice 10 voip destination-pattern 14... tech-prefix 14#

Usage Guidelines
This command applies to both the Cisco 3600 series and the Cisco MC3810.
Use the type command to specify the E&M interface for a particular voice port. With 1, the tie-line equipment generates the E-signal to the PBX type grounding the E-lead. The tie-line equipment detects the M-signal by detecting current flow to ground. If you select 1, a common ground must exist between the line equipment and the PBX.
With 2, the interface requires no common ground between the equipment, thereby avoiding ground loop noise problems. The E-signal is generated toward the PBX by connecting it to SG. The M-signal is indicated by the PBX connecting it to SB. While Type 2 interfaces do not require a common ground, they do have the tendency to inject noise into the audio paths because they are asymmetrical with respect to the current flow between devices.
|
Note E&M Type 4 is not a supported option. However, Type 4 operates similarly to Type 2 except for the M-lead operation. On Type 4, the M-lead states are open/ground, compared to Type 2, which is open/battery. Type 4 can interface with Type 2. To use Type 4 you can set the E&M voice port to Type 2 and perform the necessary M-lead rewiring. |
With 3, the interface operates the same as Type 1 interfaces with respect to the E-signal. The M-signal, however, is indicated by the PBX connecting it to SB on assertion and alternately connecting it to SG during inactivity. If you select 3, a common ground must be shared between equipment.
With 5, the Type 5 line equipment indicates E-signal to the PBX by grounding the E-lead. The PBX indicates M-signal by grounding the M-lead. A Type 5 interface is quasi-symmetrical in that while the line is up, current flow is more or less equal between the PBX and the line equipment, but noise injection is a problem.
Examples
The following example selects Type 3 as the interface type for your voice port on the Cisco 3600 series:
voice-port 1/0/0 type 3
The following example selects Type 3 as the interface type for your voice port on the Cisco MC3810:

Modification
Usage Guidelines
VFCs come with a single bundled image, VCWare, stored in VFC Flash memory. Use the unbundle vfc command to unbundle this bundled image into separate files, which are then written to Flash memory. When VCWare is unbundled, it automatically adds DSPWare to Flash memory, creates both the capability and default file lists, and populates these lists with the default files for that version of VCWare. The default file list includes the files that will be used to boot up the system. The capability list defines the available voice codecs for H.323 capability negotiation. These files are used during initial card configuration and for subsequent firmware upgrades.
Before unbundling a VFC software image that you have just copied over to VFC flash, use the clear vfc command. Unbundling a DSP firmware set rewrites the default-file and capabilities lists. After unbundling, you must reload the router for any changes to take effect.
Examples
The following example unbundles the high-complexity firmware set into slot 2:
router# unbundle high-comp vfc 2

Syntax Description
local-zone-name The name or zone name of the gatekeeper, which is usually the fully domain-qualified host name of the gatekeeper. For example, if the domain name is cisco.com, the gatekeeper name might be gk1.cisco.com. However, if the gatekeeper is controlling multiple zones, the name of the gatekeeper for each zone should be a unique string that has a mnemonic value. default Defines the default proxy policy for all calls that are not defined by a use-proxy command with the remote-zone keyword. remote-zone remote-zone-name Defines a proxy policy for calls to or from a specific remote gatekeeper or zone. inbound-to Applies the proxy policy to calls that are inbound to the local zone from a remote zone. Each use-proxy command defines the policy for only one direction. outbound-from Applies the proxy policy to calls that are outbound from the local zone to a remote zone. Each use-proxy command defines the policy for only one direction. gateway Defines the type of local device to which the policy applies. The gateway option applies the policy only to local gateways. terminal Defines the type of local device to which the policy applies. The terminal option applies the policy only to local terminals.
Defaults
The local zone uses proxy for both inbound and outbound calls to and from the local H.323 terminals only. Proxy is not used for both inbound and outbound calls to and from local gateways.

Release
Modification
Usage Guidelines
This command replaces the zone access command used in the previous versions of the gatekeeper. When a previous version of gatekeeper is upgraded, any zone access commands are translated to use-proxy commands. You can use the show gatekeeper zone status command to see the gatekeeper proxy configuration.
Examples
In the following example, the local zone sj.xyz.com is configured to use a proxy for inbound calls from remote zones tokyo.xyz.com and milan.xyz.com to gateways in its local zone. The sj.xyz.com zone is also configured to use a proxy for outbound calls from gateways in its local zone to remote zones tokyo.xyz.com and milan.xyz.com:
use-proxy sj.xyz.com remote-zone tokyo.xyz.com inbound-to gateway use-proxy sj.xyz.com remote-zone tokyo.xyz.com outbound-from gateway use-proxy sj.xyz.com remote-zone milan.xyz.com inbound-to gateway use-proxy sj.xyz.com remote-zone milan.xyz.com outbound-from gateway
Because the default mode disables proxy communications for all gateway calls, only the gateway call scenarios listed above can use the proxy.
In the following example, the local zone sj.xyz.com uses a proxy for only those calls that are outbound from H.323 terminals in its local zone to the specified remote zone germany.xyz.com:
no use-proxy sj.xyz.com default outbound-from terminal use-proxy sj.xyz.com remote-zone germany.xyz.com outbound-from terminal
Note that any calls inbound to H.323 terminals in the local zone sj.xyz.com from the remote zone germany.xyz.com use the proxy because the default applies.
The following example shows how to remove one or more proxy statements for the remote zone germany.xyz.com from the proxy configuration list:
no use-proxy sj.xyz.com remote-zone germany.xyz.com
The command above removes all special proxy configurations for the remote zone germany.xyz.com. After you enter a command like this, all calls between the local zone (sj.xyz.com) and germany.xyz.com are processed according to the defaults defined by any use-proxy commands that use the default option.
To prohibit proxy use for inbound calls to H.323 terminals in a local zone from a specified remote zone, enter a command similar to the following command:
no use-proxy sj.xyz.com remote-zone germany.xyz.com inbound-to terminal
This command overrides the default and disables proxy use for inbound calls from remote zone germany.xyz.com to all H.323 terminals in the local zone sj.xyz.com.

Usage Guidelines
Use the vad command to enable voice activity detection. With VAD, silence is not sent over the network, only audible speech. If you enable VAD, the sound quality is slightly degraded, but the connection monopolizes much less bandwidth. If you use the no form of this command, VAD is disabled and voice data is continuously sent to the IP backbone.
On the Cisco MC3810, VAD can also be assigned to the voice port using the vad voice-port configuration command. On the Cisco MC3810, if you enable VAD on the dial peer for Voice over Frame Relay switched calls or permanent calls, the dial peer setting overrides the VAD setting on the voice port.

Modification
Usage Guidelines
For switched-vofr calls, use the vofr cisco or vofr call-control command on the Cisco 2600 series, 3600 series, and 7200 series routers. Switched-vofr calls cannot be made using the vofr command by itself, or the vofr data cid command.
When the vofr command is used without the cisco keyword, all subchannels on the DLCI are configured for FRF.11 encapsulation. If the vofr command is entered without any keywords or arguments, the data subchannel will be CID 4 and there will be no call-control subchannel.
Table 69 describes special conditions and restrictions for the use of the vofr command on the Cisco MC3810.
| Type of Call | Conditions and Restrictions |
|---|---|
FRF.11 trunks |
|
Cisco trunks | Must use vofr cisco. |
switched-vofr | Must use vofr cisco. |
|
Note On the Cisco MC3810 only, the vofr cisco command performs the same function as the frame-relay interface-dlci voice-encap interface configuration command. Either command is required to enable Voice over Frame Relay. The vofr cisco command and the frame-relay interface-dlci voice-encap command are mutually exclusive, so you must choose which command to use. The vofr cisco command uses weighted fair queueing, which reduces the throughput but provides greater control over the queueing function. The frame-relay interface-dlci voice-encap option does not support queueing, which provides greater throughput. |
If the data keyword is selected, a numeric value must be entered to complete the command. If the call-control keyword is selected, you need not enter a numeric value if you wish to accept the default call-control subchannel. See the examples below for clarification.
When the vofr command is used on a Cisco MC3810 without the cisco keyword, switched calls are not permitted. Only permanent FRF.11-trunk calls can be made.
|
Note It is not possible to configure the call-control keyword on a Cisco MC3810. If this option is configured, the setting is ignored. |
Examples
The following example shows how to enable VoFR on Serial 1/1, DLCI 100 on a Cisco 2600 series, 3600 series, or 7200 series router or on an MC3810 concentrator, starting from global configuration mode:
interface serial 1/1 frame-relay interface-dlci 100 vofr
The above example configures CID 4 for data; no call-control CID is defined.
The following example configures CID 4 for data, CID 5 for call-control (both defaults):

Modification
Usage Guidelines
This command applies only to routers acting as tandem nodes in a Voice over Frame Relay environment.
This command is used for a configuration in which a tandem router is configured with multiple dial peer entries that route a call to the same destination number, but on different destination routers. In this configuration, after all routes to the first router entry in the dial-peer list are active, a new call will not "roll over" to the next router in the dial-peer list.
This failure to route to the second destination router happens when the bandwidth on the Voice over Frame Relay interface is greater than the maximum capacity of the first destination router. This condition allows the tandem router to attempt to place a new call to the first router because it has indications from the first router that there is more capacity based on the bandwidth setting. When the first destination router receives the call, if all of the ports are in use, the destination router returns a "user-busy" disconnect reason code to the tandem router. The tandem router interprets the disconnect reason code as meaning there is no available destination for the call, causing it to return a busy tone to the initiating caller
The tandem router fails to try other routers in the dial-peer list after receiving a "user disconnect" reason code, and so it terminates the call attempt. Using this command, you can perform dial-peer hunting on multiple destination routers even if the tandem router receives a "user-busy" disconnect reason code from one of the destination routers.
Examples
The following example configures the tandem router to continue dial-peer hunting if it receives a "user-busy" disconnect code from a destination router:

zone access local-zone-name {default | remote-zone remote-zone-name}{direct | proxied}
Syntax Description
local-zone-name Name of local zone (synonymous with local gatekeeper). default Use with the direct or proxied keyword to define the mode of behavior for all remote zones that have not been specially named using the remote-zone remote-zone-name keyword and argument combination. remote-zone remote-zone-name Name of remote zone (synonymous with remote gatekeeper) for which a special mode of behavior is defined. direct Configures direct calls (without use of proxies) between endpoints. The local zone (or gatekeeper) offers the local endpoint IP address instead of a local proxy's IP address. proxied Configures calls using proxies between endpoints. The local zone (or gatekeeper) offers the local proxy's IP address instead of the local endpoint's address.
Defaults
The local zone allows proxied access for all remote zones.
Command Modes

Command History

Release
Modification
Usage Guidelines
By default, a gatekeeper will offer a local proxy IP address when queried by a remote gatekeeper about a target local endpoint. This is considered proxied access. By using the zone access command, you can configure the local gatekeeper to offer the local endpoint address instead of the local proxy address. This is considered direct access.
|
Note The zone access command, configured on your local gatekeeper, only affects the use of proxies for incoming calls (that is, it does not affect the use of local proxies for outbound calls). When originating a call, a gatekeeper will use a proxy only if the remote gatekeeper offers a proxy at the remote end. A call between two endpoints in the same zone will always be a direct (nonproxied) call. |
You can define the accessibility behavior of a local zone relative to certain remote zones using the remote-zone remote-zone-name keyword and argument combination with the direct or proxied keyword. You can define the default behavior of a local zone relative to all other remote zones using the default keyword with the direct or proxied keywords. To remove an explicitly named remote zone so that it is governed by the default-behavior rule, use the no zone access command.
Examples
The following example allows direct access to the local zone eng.xyz.com from remote zones within xyz corporation. All other remote locations will have proxied access to eng.xzy.com.
zone local eng.xyz.com xyz.com zone access eng.xyz.com remote-zone mfg.xyz.com direct zone access eng.xyz.com remote-zone mktg.xyz.com direct zone access eng.xyz.com remote-zone sales.xyz.com direct zone access eng.xyz.com default proxied
The following example supposes that only local gatekeepers within xyz.com have direct access to each other because your corporation has firewalls or you do not advertise your gatekeepers externally. You have excellent QoS within your corporate network, except for a couple of foreign offices. In this case, use proxies with the foreign offices (in Milan and Tokyo) and nowhere else.

Syntax Description
gatekeeper-name The gatekeeper's name or zone name. This is usually the fully domain-qualified host name of the gatekeeper. For example, if the domain-name is cisco.com, the gatekeeper-name might be gk1.cisco.com. However, if the gatekeeper is controlling multiple zones, the gatekeeper-name for each zone should be some unique string that has a mnemonic value. domain-name The domain name served by this gatekeeper. rasIPaddress (Optional) The IP address of one of the interfaces on the gatekeeper. When the gatekeeper responds to gatekeeper discovery messages, it signals the endpoint or gateway to use this address in future communications.
Note Setting this address for one local zone makes it the address used for all local zones.
Defaults
No local zone is defined.

Release
Modification
Usage Guidelines
Multiple local zones can be defined. The gatekeeper manages all configured local zones. Intra-zone and inter-zone behavior remains the same (zones are controlled by the same or different gatekeepers).
Only one rasIPaddress argument can be defined for all local zones. You cannot configure each zone to use a different RAS IP address. If you define this in the first zone definition, you can omit it for all subsequent zones, which automatically pick up this address. If you set it in a subsequent zone local command, it changes the RAS address of all previously configured local zones as well. Once defined, you can change it by re-issuing any zone local command with a different rasIPaddress argument.
If the rasIPaddress argument is an HSRP virtual address, it automatically puts the gatekeeper into HSRP mode. In this mode, the gatekeeper assumes STANDBY or ACTIVE status according to whether the HSRP interface is on STANDBY or ACTIVE status.
You cannot remove a local zone if there are endpoints or gateways registered in it. To remove the local zone, shut down the gatekeeper first, which forces unregistration.
Multiple zones are controlled by multiple logical gatekeepers on the same Cisco IOS platform.
The maximum number of local zones defined in a gatekeeper should not exceed 100.
This command can also be used to change the IP address used by the gatekeeper.
Examples
The following example creates a zone controlled by a gatekeeper in the domain called cisco.com:
zone local gk1.cisco.com cisco.com

Command
Description
Syntax Description
gatekeeper-name The name of a local or remote gatekeeper, which must have been defined by using the zone local or zone remote command. e164-prefix An E.164 prefix in standard form followed by dots (.). Each dot represent a number in the E.164 address. For example, 212....... is matched by 212 and any seven numbers. Note Although a dot representing each digit in an E.164 address is the preferred configuration method, you can also enter an asterisk (*) to match any number of digits. gw-priority pri-0-to-10 gw-alias (Optional) Use the gw-priority option to define how the gatekeeper selects gateways in its local zone for calls to numbers beginning with prefix e164-prefix. Do not use this option to set priority levels for a prefix assigned to a remote gatekeeper. Use values from 0 to 10. A 0 value prevents the gatekeeper from using the gateway gw-alias for that prefix. Value 10 places the highest priority on gateway gw-alias. If you do not specify a priority value for a gateway, the value 5 is assigned. To assign the same priority value for one prefix to multiple gateways, list all the gateway names after the pri-0-to-10 value. The gw-alias name is the H.323 ID of a gateway that is registered or will register with the gatekeeper. This name is set on the gateway with the h323-gateway voip h.323-id command.
Defaults
No knowledge of its own prefix or the prefix of any other zone is defined.

Usage Guidelines
A gatekeeper can handle more than one zone prefix, but a zone prefix cannot be shared by more than one gatekeeper. If you have defined a zone prefix as being handled by a gatekeeper and now define it as being handled by a second gatekeeper, the second assignment cancels the first.
If you need a gatekeeper to handle more than one prefix, but for cost reasons you want to be able to group its gateways by prefix usage, there are two ways to do it.
The first method is simpler, has less overhead, and is recommended if your gateways can be divided into distinct groups, where each group is to be used for a different set of prefixes. For instance, if a group of gateways is used for calling area codes 408 and 650, and another group is used for calling area code 415, you can use this method. In this case, you define a local zone for each set of prefixes, and have the group of gateways to be used for that set of prefixes register with that specific local zone. Do not define any gateway priorities. All gateways in each local zone are treated equally in the selection process.
However, if your gateways cannot be cleanly divided into nonintersecting groups (for instance if one gateway is used for calls to 408 and 415 and another gateway is used for calls to 415 and 650, and so on), you can put all these gateways in the same local zone and use the gw-priority option to define which gateways will be used for which prefixes.
When choosing a gateway, the gatekeeper first looks for the longest zone prefix match; then it uses the priority and the gateway status to select from the gateways. If all gateways are available, the gatekeeper chooses the highest priority gateway. If all the highest priority gateways are busy (see the gateway resource threshold command), a lower priority gateway is selected.
|
Note The zone prefix command matches a prefix to a gateway. It does not register the gateway. The gateway must register with the gatekeeper before calls can be completed through that gateway. |
Examples
The following example shows how you can define multiple local zones for separating your gateways:
zone local gk408or650 xyz.com zone local gk415 xyz.com zone prefix gk408or650 408....... zone prefix gk408or650 650....... zone prefix gk415 415.......
Now you need to configure all the gateways to be used for area codes 408 or 650 to register with gk408or650 and all gateways to be used for area code 415 to register with gk415. On Cisco voice gateways, you configure the gateways to register with the appropriate gatekeepers by using the h323 voip id command.
The following example shows how you can put all your gateways in the same zone but use the gw-priority keyword to determine which gateways will be used for calling different area codes:
zone local localgk xyz.com zone prefix localgk 408....... zone prefix localgk 415....... gw-pri 10 gw1 gw2 zone prefix localgk 650....... gw-pri 0 gw1
The commands shown accomplish the following tasks:
A priority 0 is assigned to gateway gw1 to exclude it from the gateway pool for prefix 650........ When gateway gw2 registers with gatekeeper localgk, it is added to the gateway pool for each prefix as follows:
The following example changes gateway gw2 from priority 10 for zone 415....... to the default priority 5:
no zone prefix localgk 415....... gw-pri 10 gw2
The following example changes both gateways gw1 and gw2 from priority 10 for zone 415....... to the default priority 5:
no zone prefix localgk 415....... gw-pri 10 gw1 gw2
In the preceding example, the prefix 415....... remains assigned to gatekeeper localgk. All gateways that do not specify a priority level for this prefix are assigned a default priority of 5. The following example removes the prefix and all associated gateways and priorities from this gatekeeper:
no zone prefix localgk 415.......

Usage Guidelines
All gatekeepers do not have to be in DNS. For those that are not, use the zone remote command so that the local gatekeeper knows how to access them. In addition, you may wish to improve call response time slightly for frequently accessed zones. If the zone remote command is configured for a particular zone, you do not need to make a DNS lookup transaction.
The maximum number of zones defined on a gatekeeper varies depending on the mode or the call model or both. For example, a directory gatekeeper may be in the mode of being responsible for forwarding LRQs and not handling any local registrations and calls; The call model might be E.164 addressed calls instead of H.323-ID addressed calls.
For a directory gatekeeper that does not handle local registrations and calls, the maximum remote zones defined should not exceed 10,000; An additional 4 MB of memory is required to store this maximum number of remote zones.
For a gatekeeper that handles local registrations and only E.164 addressed calls, the number of remote zones defined should not exceed 2000.
For a gatekeeper that handles H.323-ID calls, the number of remote zones defined should not exceed 200.
Examples
The following example configures the local gatekeeper to reach targets of the form xxx.cisco.com by sending queries to the gatekeeper named sj3.cisco.com at IP address 1.2.3.4:
zone remote sj3.cisco.com cisco.com 1.2.3.4

You can use the zone subnet command more than once to create a list of subnets controlled by a gatekeeper. The subnet masks do not have to match actual subnets in use at your site. For example, to specify a particular endpoint, you can supply its address with a 32-bit netmask.
Examples
The following example starts by disabling the gatekeeper, gk1.cisco.com, from accepting discovery and registration messages from all subnets. Next, gk1.cisco.com is configured to accept discovery and registration messages from all H.323 nodes on the subnet 172.21.127.0. In addition, gk1.cisco.com is configured to accept discovery and registration messages from a particular endpoint with the IP address 172.21.128.56.
