Command Modes

Command History

Release	Modification
12.0(5)XE and 12.0(7)T	This command was introduced.

Usage Guidelines

Codec complexity refers to the amount of processing required in order to perform compression. Codec complexity affects the number of calls that can take place on the DSPfarm interfaces, referred to as call density. The greater the codec complexity, the fewer calls are handled. For example, G.711 requires less DSP processing than G.728, so that as long as the bandwidth is available, more calls can be handled simultaneously by using the G.711 standard than using G.728.

The DSP interface dspfarm codec complexity setting affects the options available for the codec dial-peer configuration command.

To change codec complexity, you must first remove any configured CAS or DS0 groups, and then reinstate them after the change.

Examples

The following example configures the DSPfarm interface 1/0 on the Cisco 7200 series routers to support high compression:

dspint dspfarm 1/0 
			 codec high 0-30

11.3(1)T	This command was introduced.
11.3(3)T	Support for Cisco 2600 series routers was added.
12.0(3)T	Support for the Cisco AS5300 access server was added.
12.0(4)T	This command was modified for VoFR dial peers, and support for this command was extended to the Cisco MC3810.
12.0(5)XK and 12.0(7)T	Additional codec choices and other options were added.

Usage Guidelines

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

A specific codec type can be configured on the dial-peer as long as it is supported by the setting used with the codec complexity voice-card configuration command. The codec complexity command is voice-card-specific and platform-specific.

The codec dial-peer configuration command is particularly useful when you must change to a small-bandwidth codec. Large-bandwidth codecs, such as G.711, do not fit in a small-bandwidth link. However, the g711alaw and g711ulaw codecs provide higher-quality voice transmission than other codecs. The g729r8 codec provides near-toll quality with considerable bandwidth savings.

If codec values for the dial peers of a connection do not match, the call fails.

You can change the payload of each VoIP frame by using the bytes setting; you can change the payload of each VoFR frame by using the bytes keyword with the payload_size setting. However, increasing the payload size can add processing delay for each voice packet.

For toll quality, use the g711alaw or g711ulaw keyword. 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 keyword.

On the Cisco MC3810, this command was first supported as a voice port command. This command does not apply to the Cisco 7200 series routers.

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(4)T, 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 begins in global configuration mode and is for VoFR dial peer 200.

dial-peer voice 200 vofr
 codec g711alaw bytes 120

The following example configures a voice coder rate for VoIP dial peer 10 that provides toll quality but uses a relatively high amount of bandwidth:

dial-peer voice 10 voip
 codec g711alaw

Usage Guidelines

Use the comfort-noise command to generate background noise to fill silent gaps during calls if VAD is activated. If the comfort-noise command is not enabled, and VAD is enabled at the remote end of the connection, the user will hear dead silence when the remote party is not speaking.

The configuration of the comfort-noise command only affects the silence generated at the local interface; it does not affect the use of VAD on either end of the connection or the silence generated at the remote end of the connection.

Note On the Cisco MC3810, this command cannot be disabled.

Examples

The following example enables background noise on the Cisco 3600 series:

voice-port 1/0/0
 comfort-noise

ignore	Specifies the E&M or E&M MEL CAS voice port on the Cisco MC3810 multiservice concentrator to ignore specific receive bits.

Syntax Description

plar	Specifies a private line auto ring down (PLAR) connection. PLAR is handled by associating a peer directly with an interface; when an interface goes off-hook, the peer is used to set up the second call leg and conference them together without the caller having to dial any digits.
tie-line	(This keyword is specific to the Cisco MC3810.) Specifies a tie-line connection to a private branch exchange (PBX).
plar-opx	(This keyword is specific to the Cisco MC3810) Specifies a PLAR Off-Premises eXtension connection. Using this option, the local voice-port provides a local response before the remote voice-port receives an answer. On FXO interfaces, the voice-port will not answer until the remote side answers.
string	Specifies the destination telephone number. Valid entries are any series of digits that specify the E.164 telephone number.
trunk	Specifies a straight tie-line connection to a private branch exchange (PBX).
string	Specifies the destination telephone number. Valid entries are any series of digits that specify the E.164 telephone number.
answer-mode	(Optional; used only with the trunk keyword.) Specifies that the router should not attempt to initiate a trunk connection, but should wait for an incoming call before establishing the trunk.

Defaults

No connection mode is specified.

11.3(1)T	This command was introduced.
11.3(1)MA1	This command was first supported on the Cisco MC3810, and the tie-line keyword was made available on the Cisco MC3810.
11.3(1)MA5	The plar-opx keyword was first made available on the Cisco MC3810 as the plar-opx-ringrelay keyword. The keyword was shortened in a subsequent release.
12.0(3)XG	The trunk keyword was made available on the Cisco MC3810. The trunk answer-mode option was added.

Usage Guidelines

Use the connection command to specify a connection mode for a specific interface. For example, use the connection plar command to specify a PLAR interface. The string you configure for this command is used as the called number for all calls coming in over this connection. The destination peer is determined by called number.

To configure virtual trunk connections in Voice over IP, the following restrictions apply:

• You can use the following voice port combinations:

  • E&M to E&M (same type)

  • FXS to FXO

  • FXS to FXS (with no signalling)

• Do not perform number expansion on the destination pattern telephone numbers configured for trunk connection.

• Configure both end routers for trunk connections.

• The connected Cisco routers must be Cisco 2600 or Cisco 3600 series routers.

Note Because virtual trunk connections do not support number expansion, the destination patterns on each side of the trunk connection must match exactly.

If you desire one of the devices in a static trunk connection to act as slave and receive calls only, use the answer-mode option with the connection trunk command when configuring that device.

Note When using the connection trunk command, you must perform a shutdown/no shutdown command sequence on the voice port.

VoIP establishes the trunk connection immediately after it is configured. Both ports on either end of the connection are dedicated until you disable trunking for that connection. If for some reason the link between the two switching systems goes down, the virtual trunk re-establishes itself after the link comes back up.

The connection tie-line command is used on the Cisco MC3810 when a dial plan requires that additional digits are added in front of any digits dialed by the PBX, and that the combined set of digits are used to route the call via the dial-peers and into the network. The operation is similar to the connection plar command operation, but in this case the tie-line port also waits to collect digits from the PBX. The tie-line digits are also automatically stripped by a terminating port.

If the connection command is not configured, the standard session application outputs a dial tone when the interface goes off-hook until enough digits are collected to match a dial-peer and complete the call.

Examples

The following example selects PLAR as the connection mode on the Cisco 3600 series, with a destination telephone number of 555-9262:

voice-port 1/0/0
 connection plar 5559262
 

The following example selects tie-line as the connection mode on the Cisco MC3810, with a destination telephone number of 555-9262:

12.0(4)XJ	This command was modified for Store and Forward Fax.

Usage Guidelines

Use the destination-pattern command to define the E.164 telephone number for a dial peer.

This pattern is used to match dialed digits to a dial peer. The dial peer is then used to complete the call. When a router receives voice data, it compares the called number (the full E.164 telephone number) in the packet header with the number configured as the destination pattern for the voice-telephony peer. The router then strips out the left-justified numbers corresponding to the destination pattern. If you have configured a prefix, the prefix is appended to the front of the remaining numbers, creating a dial string, which the router then dials. If all numbers in the destination pattern are stripped-out, the user receives a dial tone.

There are certain areas in the world (for example, in certain European countries) where valid telephone numbers can vary in length. Use the optional control character t to indicate that a particular destination-pattern value is a variable-length dial string. In this case, the system does not match the dialed numbers until the interdigit timeout value has expired.

Note The Cisco IOS software does not check the validity of the E.164 telephone number; it accepts any series of digits as a valid number.

Examples

The following example configures the E.164 telephone number, 555-7922, for a dial peer:

dial-peer voice 10 pots

Usage Guidelines

There are certain areas in the world (for example, in certain European countries) where valid telephone numbers can vary in length. When a dialed-number string has been identified as a variable length dialed-number, the system waits until the configured value for the timeouts interdigits command has expired before placing the call. To avoid waiting until the interdigit timeout value has expired, you can designate a special character as a terminator---meaning that when you dial that character, the system no longer waits for any additional digits and places the call. Use the dial-peer terminator global configuration command to designate a particular character as a terminator.

Examples

The following example configures # as the special terminating character for variable-length dialed-numbers:

configure terminal
 dial-peer terminator #

12.0(4)T	Added vofr keyword support for the Cisco 7200 series platform.
12.0(4)XJ	Added mmoip keyword support for the Cisco AS5300 platform.

Usage Guidelines

Use the dial-peer voice global configuration command to switch to dial-peer configuration mode from global configuration mode and to define a particular dial peer. Use the exit command to exit dial-peer configuration mode and return to global configuration mode.

After you have created a dial peer, that dial peer remains defined and active until you disable that particular dial peer. To disable a dial peer, use the no form of this command.

In Store and Forward Fax on the Cisco AS5300, the POTS dial peer defines the inbound faxing line characteristics from the sending fax device to the receiving Cisco AS5300 and the outbound line characteristics from the sending Cisco AS5300 to the receiving fax device. The MMoIP dial peer defines the inbound faxing line characteristics from the Cisco AS5300 to the receiving SMTP mail server. This command applies to both on-ramp and off-ramp Store and Forward Fax functions.

Examples

The following example shows how to access dial-peer configuration mode and configure a POTS peer identified as dial peer 100, starting from global configuration mode:

configure terminal
 dial-peer voice 100 pots
 

The following example accesses dial-peer configuration mode and configures a POTS peer identified as dial peer 10 and an MMoIP dial peer identified as dial peer 20:

configure terminal
 dial-peer voice 10 pots
 dial-peer voice 20 mmoip
 
 

The following example disables the MMoIP peer identified as dial peer 20:

configure terminal
 no dial-peer voice 20

Usage Guidelines

This command applies to both the Cisco MC3810 and the Cisco 3600 series.

Use the dial-type command to specify an out-dialing type for an FXO or E&M voice port interface; this command is not applicable to FXS voice ports because they do not generate out-dialing. Voice ports can always detect dtmf and pulse signals. This command does not affect voice port dialing detection.

The dial-type command affects out-dialing as configured for the dial peer.

Examples

The following example configures a voice port on the Cisco 3600 series to support a touch-tone dialer:

voice-port 1/0/0
 dial-type dtmf
 

The following example configures a voice port on the Cisco MC3810 to support a rotary (pulse tone) dialer:

voice-port 1/1
 dial-type pulse

Syntax Description

This command has no arguments or keywords.

Usage Guidelines

Use the direct-inward-dial command to enable the DID call treatment for the incoming called numbers. When this feature is enabled, the incoming call is treated as if the digits are received from the DID trunk. The called number is used to select the outgoing dial peer. No dial tone will be presented to the caller.

Use the no form of this command to disable DID. When disabled, the called number is used to select the outgoing dial peer. The caller will be prompted for a called number via dial tone.

This command is only applicable to POTS dial peers. This command applies to on-ramp Store and Forward Fax functions.

Examples

The following example enables DID call treatment for incoming called numbers:

dial peer voice 10 pots
