Command History

Release	Modification
11.3(1)T	This command was first introduced for VoIP dial peers.
12.0(3)XG	This command was modified for VoFR dial peers. On the Cisco MC3810, this command was first supported as a dial-peer command.
12.1(2)E	This command was introduced for Cisco 7500 series routers with a Versatile Interface Processor.

Usage Guidelines

Use this command to define a specific voice coder rate of speech and payload size for a VoFR dial peer.

Note You cannot define a CODEC payload size for a VoIP dial peer.

A Cisco 7500 series router requires a Versatile Interface Processor to utilize this command.

This command does not apply to the Cisco 7200 series routers.

For toll quality, use g711alaw or g711ulaw. These values provide high-quality voice transmission but use a significant amount of bandwidth. For almost toll quality (and a significant savings in bandwidth), use the g729r8 value.

On the Cisco MC3810, you can also assign CODEC values to the voice port. If configuring calls to a Cisco MC3810 running software versions prior to 12.0(3)XG, configure the codec command on the voice port. If configuring Cisco-trunk permanent calls, configure the codec command on the dial peer. If you configure the codec command on the dial peer for Voice over Frame Relay permanent calls on the Cisco MC3810, the dial peer codec command setting overrides the codec setting configured on the voice port.

Note For regular switched calls on the Cisco MC3810, the CODEC value must be configured on the voice port, and the voice payload size is not configurable.

Examples

The following example shows how to configure a voice coder rate that provides toll quality voice with a payload of 120 bytes per voice frame on a Cisco 2600 series or 3600 series router acting as a terminating node. The example configuration, starting from global configuration mode, is for VoFR dial peer 200:

router(config)# dial-peer voice 200 vofr
router(config-dial-peer)# codec g711alaw bytes 120
router(config-dial-peer)#

11.3(1)T	This command was first introduced.
12.0(3)XG	This command was first supported on the Cisco MC3810.
12.1(2)E	This command was introduced for Cisco 7500 series routers with a Versatile Interface Processor.

Usage Guidelines

Use this command to specify the fax transmission rate to the specified dial peer.

A Cisco 7500 series router requires a Versatile Interface Processor to utilize this command.

The values for this command apply only to the fax transmission speed and do not affect the quality of the fax itself. The higher values provide a faster transmission speed but monopolize a significantly larger portion of the available bandwidth. Slower transmission speeds use less bandwidth.

If the fax-rate transmission speed is set higher than the CODEC rate in the same dial peer, the data sent over the network for fax transmission will be above the bandwidth reserved for RSVP. Because more network bandwidth will be monopolized by the fax transmission, Cisco does not recommend setting the fax-rate value higher than the value of the selected CODEC. If the fax-rate value is set lower than the CODEC value, faxes will take longer to transmit but will use less bandwidth.

Examples

The following example configures a transmission speed of 9600 bps for faxes sent to a dial peer:

router(config)# dial-peer voice 100 vofr
router(config-dial-peer)# fax-rate 9600
router(config-dial-peer)#

12.1(2)E	This command was introduced for Cisco 7500 series routers with a Versatile Interface Processor.

Usage Guidelines

A Cisco 7500 series router requires a Versatile Interface Processor to utilize this command.

This command is typically used for subinterfaces; however, it can also be used on main interfaces. Using the frame-relay interface-dlci command on main interfaces enables the use of routing protocols on interfaces that use Inverse ARP. The frame-relay interface-dlci command on a main interface is also valuable for assigning a specific class to a single PVC where special characteristics are desired. Subinterfaces are logical interfaces associated with a physical interface. You must specify the interface and subinterface before you can use this command to assign any DLCIs and any encapsulation or broadcast options. See the "Examples" section for the sequence of commands.

This command is required for all point-to-point subinterfaces; it is also required for multipoint subinterfaces for which dynamic address resolution is enabled. It is not required for multipoint subinterfaces configured with static address mappings.

For more information about automatically installing router configuration files over a Frame Relay network, see the "Loading System Images and Microcode" chapter in the Configuration Fundamentals Configuration Guide.

Examples

The following example assigns DLCI 100 to a serial interface, starting from global configuration mode:

router(config)# interface serial 1/1
router(config-if)# frame-relay interface-dlci 100
router(config-fr-dlci)# 
 

The following example enables Voice over Frame Relay on DLCI 100 on a Cisco MC3810 and sets the data fragmentation size to 80 bytes:

router(config)# interface serial0
router(config-if)# frame-relay interface-dlci 100 voice-encap 80
router(config-fr-dlci)# 
 

The following example enables Voice over Frame Relay on DLCI 100 on a Cisco MC3810, sets the data fragmentation size to 80 bytes, and sets the voice CIR to 24000 bps:

router(config)# interface serial0
router(config-if)# frame-relay interface-dlci 100 voice-encap 80 voice-cir 24000
router(config-fr-dlci)#

Use the session target command to specify a network-specific address or domain name for a dial peer. Whether you select a network-specific address or a domain name depends on the session protocol you select.

For VoFR dial peers, the "cid" option is not allowed when using the "cisco-switched" session protocol.

The session target loopback command is used for testing the voice transmission path of a call. The loopback point will depend on the call origination and the loopback type selected.

The session target dns command can be used with or without the specified wildcards. Using the optional wildcards can reduce the number of VoIP dial peer session targets you need to configure if you have groups of numbers associated with a particular router.

A Cisco 7500 series router requires a Versatile Interface Processor to utilize this command.

Examples

The following example shows how to configure serial interface 1/0, DLCI 100 as the session target for VoFR dial peer 200 (an FRF.11 dial peer) on a Cisco 2600, 3600, or 7500 series router, starting from global configuration mode and using the "frf11-trunk" session protocol:

router(config)# dial-peer voice 200 vofr
router(config-dial-peer)# destination-pattern 13102221111
router (config-dial-peer)# called-number 5552150
router(config-dial-peer)# session protocol frf11-trunk
router (config-dial-peer)# session target serial 1/0 100 20
router(config-dial-peer)# 
 

The following example shows how to configure serial interface 1/1, DLCI 200 as the session target for switched VoFR dial peer 400 on a Cisco 2600, 3600, 7200, or 7500 series router, using the "cisco-switched" session protocol and starting from global configuration mode:

router(config)# dial-peer voice 400 vofr
router(config-dial-peer)# destination-pattern 13102221111
router (config-dial-peer)# session target serial 1/1 200
router(config-dial-peer)# 
 

The following example configures a session target for a VoFR dial peer on a Cisco MC3810 with a session target on serial port #1 and a DLCI of 200:

router(config)# dial-peer voice 11 vofr
router(config-dial-peer)# destination-pattern 13102221111
router (config-dial-peer)# session target Serial1 200
router(config-dial-peer)# 
 

The following example configures a session target for a VoIP dial peer using DNS for a host, "voice_router," in the domain "cisco.com:"

voip(config)# dial-peer voice 10 voip
voip (config-dial-peer)# session target dns:voice_router.cisco.com
voip(config-dial-peer)# 
 

The following example configures a session target for a VoIP dial peer using DNS, with the optional $u$. wildcard. In this example, the destination pattern has been configured to allow for any four-digit extension, beginning with the numbers 1310222. The optional wildcard $u$. indicates that the router will use the unmatched portion of the dialed number---in this case, the four-digit extension, to identify the dial peer. As in the previous example, the domain is "cisco.com."

voip(config)# dial-peer voice 10 voip
voip (config-dial-peer)# destination-pattern 1310222....
voip (config-dial-peer)# session target dns:$u$.cisco.com
voip (config-dial-peer)# 
 

The following example configures a session target for a VoIP dial peer using DNS, with the optional $d$. wildcard. In this example, the destination pattern has been configured for 13102221111. The optional wildcard $d$. indicates that the router will use the destination pattern to identify the dial peer in the "cisco.com" domain.

voip(config)# dial-peer voice 10 voip
voip (config-dial-peer)# destination-pattern 13102221111
voip (config-dial-peer)# session target dns:$d$.cisco.com
voip (config-dial-peer)# 
 

The following example configures a session target for a VoIP dial peer using DNS, with the optional $e$. wildcard. In this example, the destination pattern has been configured for 12345. The optional wildcard $e$. indicates that the router will reverse the digits in the destination pattern, add periods between the digits, and then use this reverse-exploded destination pattern to identify the dial peer in the "cisco.com" domain.

voip(config)# dial-peer voice 10 voip
voip (config-dial-peer)# destination-pattern 12345
voip (config-dial-peer)# session target dns:$e$.cisco.com
 

The following example configures a session target for a Voice over ATM dial peer on a Cisco MC3810. The session target is sent to ATM interface 0, and is for a PVC with a VCI of 20.

voatm(config)# dial-peer voice 12 voatm
voatm(config-dial-peer)# destination-pattern 13102221111
voatm (config-dial-peer)# session target atm0 pvc 20
voatm(config-dial-peer)# 
 

The following example configures a session target on serial port 0 for Voice over HDLC on a Cisco MC3810:

vohdlc(config)# dial-peer voice 13 vohdlc
vohdlc(config-dial-peer)# destination-pattern 13102221111
vohdlc (config-dial-peer)# session target Serial0
vohdlc(config-dial-peer)#

Command History

Release	Modification
10.0	This command was first introduced.
12.0(3)XG	This command was modified to include the fragmentation type and size associated with a particular PVC when fragmentation is enabled on the PVC.
12.1(2)E	This command was introduced for Cisco 7500 series routers with a Versatile Interface Processor.

Usage Guidelines

When "vofr" or "vofr cisco" have been configured on the PVC, and a voice bandwidth has been allocated to the class associated with this PVC, configured voice bandwidth and used voice bandwidth are also displayed.

Statistics Reporting

To obtain statistics about PVCs on all Frame Relay interfaces, use this command with no arguments.

Per VC counters are not incremented at all when either autonomous or SSE switching is configured; therefore, PVC values will be inaccurate if either switching method is used.

Traffic Shaping

If an LMI status report indicates that a PVC is not active, then it is marked as inactive. A PVC is marked as deleted if it is not listed in a periodic LMI status message.

Examples

The various displays in this section show sample output for a variety of different PVCs. Some of the PVCs carry data only; some carry a combination of voice and data.

Below is sample output from the show frame-relay pvc command for a PVC carrying Voice over Frame Relay configured via the vofr cisco command. The frame-relay voice bandwidth command has been configured on the class associated with this PVC, as has fragmentation. The fragmentation employed is Cisco proprietary.

A sample configuration for this scenario is shown first; then the output for the show frame-relay pvc command.

Serial0/0
          Switching path    Pkts In   Chars In   Pkts Out  Chars Out
               Processor       5668     447428       5663      446995

Command History

Release	Modification
11.3(1)T	This command was first introduced.
12.0(3)XG	First supported as a dial-peer command on the Cisco MC3810 (in prior releases vad was only available as a voice-port command).
12.1(2)E	This command was introduced for Cisco 7500 series routers with a Versatile Interface Processor.

Usage Guidelines

This command applies to all voice applications on the Cisco MC3810 and the Cisco 2600, 3600, and 7500 series routers.

Use the vad command to enable voice activity detection. With VAD, silence is not transmitted 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 transmitted 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.

Note On the Cisco MC3810, the vad dial-peer command is enabled by default. However, the vad voice-port command is disabled by default.

Examples

The following example enables VAD for a VoIP dial peer, starting from global configuration mode:

router(config)# dial-peer voice 200 voip
router(config-dial-peer)# vad
router(config-dial-peer)# 

Related Commands Related Commands

Command	Description
comfort-noise	Generates background noise to fill silent gaps during calls if VAD is enabled.
dial-peer voice	Enters dial-peer configuration mode and specifies a dial peer type.

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 queuing, which reduces the throughput but provides greater control over the queuing function. The frame-relay interface-dlci voice-encap option does not support queuing, which provides greater throughput.

If the "data" option is selected, a numeric value must be entered to complete the command. If the "call-control" option 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" option, switched calls are not permitted. Only permanent FRF.11-trunk calls can be made.

Note It is not possible to configure the "call-control" option 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, 3600, 7200, or 7500 series router or on an MC3810 concentrator, starting from global configuration mode:

router(config)# interface serial 1/1
router(config-if)# frame-relay interface-dlci 100
router(config-fr-dlci)# vofr
router(config-fr-dlci)# 
 

The above example configures CID 4 for data; no call-control CID is defined.

To configure CID 4 for data, CID 5 for call-control (both defaults), enter the following command:

router(config-fr-dlci)# vofr call-control
router(config-fr-dlci)# 
 

To configure CID10 for data, CID 15 for call-control, enter the following command:

router(config-fr-dlci)# vofr data 10 call-control 15
router(config-fr-dlci)# 
 

To configure CID 4 for data, CID 15 for call-control, enter the following command:

router(config-fr-dlci)# vofr call-control 15
router(config-fr-dlci)# 
 

To configure CID 10 for data, CID 5 for call-control, enter the following command:

router(config-fr-dlci)# vofr data 10 call-control
router(config-fr-dlci)# 
 

To configure CID 10 for data with no call-control, enter the following command:

router(config-fr-dlci)# vofr data 10
router(config-fr-dlci)# 
 

To configure a Cisco router or MC3810 for a VoFR application with an older release of the MC3810 (prior to Release 12.0(3)XG), enter the following command:

router(config-fr-dlci)# vofr cisco
router(config-fr-dlci)#
