Cisco IOS Voice Commands:
O
This chapter contains the commands to configure and maintain Cisco IOS voice applications. The commands are presented in alphabetical order. Some commands required for configuring voice may be found in other Cisco IOS command references. Use the master index of commands or search online to find these commands.
For detailed information on how to configure these applications and features, refer to the Cisco IOS Voice Configuration Library.
offer call-hold
To specify globally how the Session Initiation Protocol (SIP) gateway should initiate call-hold requests, use the offer call-hold command in SIP user-agent configuration mode. To disable a method of initiating call hold, use the no form of this command.
offer call-hold {conn-addr | direction-attr}
no offer call-hold {conn-addr | direction-attr}
Syntax Description
Command Default
direction-attr
Command Modes
SIP user-agent configuration
Command History
|
|
|
|---|---|
12.3(8)T |
This command was introduced. |
Usage Guidelines
Cisco SIP gateways support receiving call-hold requests in either of the two formats, but the direction attribute is recommended. Specifying a call-hold format is only available globally with the offer call-hold command; configuration is not available at the dial-peer level.
Examples
The following example initiates call hold by configuring the gateway to send a=sendonly in the Session Description Protocol (SDP). Using the direction-attr keyword is the current and preferred method to initiate call hold.
sip-ua
retry invite 3
offer call-hold direction-attr
The following example initiates call hold by configuring the gateway to send 0.0.0.0 as the IP address in the c=line.
sip-ua
retry invite 3
offer call-hold conn-addr

show sip-ua status |
Displays status for the SIP UA. |
suspend-resume |
Enables SIP Suspend and Resume functionality. |
operation
To select a specific cabling scheme for E&M ports, use the operation command in voice-port configuration mode. To restore the default, use the no form of this command.
operation {2-wire | 4-wire}
no operation {2-wire | 4-wire}
Syntax Description
2-wire |
Two-wire E&M cabling scheme. |
4-wire |
Four-wire E&M cabling scheme. |
Command Default
2-wire E&M cabling scheme
Command Modes
Voice-port configuration
Command History
|
|
|
|---|---|
11.3(1)T |
This command was introduced on the Cisco 3600 series. |
11.3(1)MA |
This command was implemented on the Cisco MC3810. |
Usage Guidelines
This command affects only voice traffic. Signaling is independent of 2-wire versus 4-wire settings. If the wrong cable scheme is specified, the user might get voice traffic in only one direction.
Using this command on a voice port changes the operation of both voice ports on a VPM card. The voice port must be shut down and then opened again for the new value to take effect.
This command is not applicable to FXS or FXO interfaces because they are, by definition, 2-wire interfaces.
Examples
The following example specifies that an E&M port uses a 4-wire cabling scheme:
voice-port 1/0/0
operation 4-wire
The following example specifies that an E&M port uses a 2-wire cabling scheme:
voice-port 1/1
operation 2-wire
options-ping
To enable in-dialog OPTIONS, use the options-ping command in global configuration mode. To disable, use the no form of this command.
options-ping seconds
no options-ping seconds
Syntax Description
seconds |
Intervals, in seconds OPTIONS transactions are sent. Range is 60-1200, there is no default. |
Command Default
This command is disabled by default.
Command Modes

12.4(11)T |
This command was introduced. |
Usage Guidelines
The in-dialog OPTIONS refresh command eanbles an alterante refresh mechanism to RTP/RTCP media inactivity timer and session timer can be used on SIP-to-SIP and SIP-to-H.323 calls. The refresh with in-dialog OPTIONS method is meant to only be hop-to-hop, and not end-to-end. Since session timer achieves similar results, the OPTIONs refresh/ping will not take affect when session timer is negotiated. The behavior on the H.323 endpoint is as if it was a TDM-SIP call. The generating in-dialog OPTIONS is enabled at the global level or dialpeer level. The system default setting is disabled. This feature can be use by both a TDM voice gateway and an IP-to-IP gateway.
Examples
The following example sets the in-dialog refresh time to 60 seconds:
Router(conf-serv-sip)# options-ping 60

outbound-proxy
To configure a Session Initiation Protocol (SIP) outbound proxy for outgoing SIP messages globally on a Cisco IOS voice gateway, use the outbound-proxy command in voice service SIP configuration mode. To globally disable forwarding of SIP messages to a SIP outbound proxy globally, use the no form of this command.
outbound-proxy {dhcp | ipv4:ip-address[:port-number] | dns:host:domain [reuse]}
no outbound-proxy
Syntax Description
Command Default
The Cisco IOS voice gateway does not forward outbound SIP messages to a proxy.
Command Modes
Voice service VoIP SIP configuration (conf-serv-sip)
Command History
Usage Guidelines
You can use the outbound-proxy command in voice service SIP configuration mode to specify outbound proxy settings globally for a Cisco IOS voice gateway. You can also use the voice-class sip outbound-proxy command in dial peer voice configuration mode to configure settings for an individual dial peer that override or defer to the global settings for the gateway. However, if both a Cisco Unified Communications Manager Express (CME) and a SIP gateway are configured on the same router, then there is a scenario that can cause incoming SIP messages from line-side phones to be confused with SIP messages coming from the network side. To avoid failed calls caused by this scenario, disable the SIP outbound proxy setting for all line-side phones on a dial peer using the outbound-proxy system command in voice register global configuration mode.
Examples
The following example shows how to specify the SIP outbound proxy globally for a Cisco IOS voice gateway using an IP address:
Router> enable
Router# configure terminal
Router(config)# voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# outbound-proxy ipv4:10.1.1.1
The following example shows how to specify the SIP outbound proxy globally for a Cisco IOS voice gateway using a destination hostname and domain:
Router> enable
Router# configure terminal
Router(config)# voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# outbound-proxy dns:sipproxy:example.com
The following example shows how to specify the SIP outbound proxy globally for a Cisco IOS voice gateway using the DHCP protocol:
Router> enable
Router# configure terminal
Router(config)# voice service voip
Router(conf-voi-serv)# sip
Router(conf-serv-sip)# outbound-proxy dhcp

outbound retry-interval
To define the retry period for attempting to establish the outbound relationship between border elements, use the outbound retry-interval command in Annex G neighbor service configuration mode. To disable the command, use the no form of this command.
outbound retry-interval interval
no outbound retry-interval
Syntax Description
interval |
Amount of time, in seconds, to establish the outbound relationship. Range is from 1 to 2147483. The default is 30. |
Defaults
30 seconds
Command Modes
Annex G neighbor service configuration (config-nxg-neigh-svc)
Command History
|
|
|
|---|---|
12.2(11)T |
This command was introduced. |
Usage Guidelines
Service relationships are defined to be unidirectional. When a service relationship is established between border element A and border element B, A is entitled to send requests to B and expect responses. For B to send requests to A and expect responses, a second service relationship must be established. From A's perspective, the service relationship it establishes with B is designated as the "outbound" service relationship.
Use this command to set the retry period for attempting to bring up the outbound relationship between border elements.
Examples
The following example shows how to set the retry interval to 300 seconds (5 minutes):
Router(config-nxg-neigh-svc)# outbound retry-interval 300

output attenuation
To configure a specific output attenuation value or enable automatic gain control, use the output attenuation command in voice-port configuration mode. To disable the selected output attenuation value, use the no form of this command.
output attenuation {decibels | auto-control [auto-dbm]}
no output attenuation {decibels | auto-control [auto-dbm]}
Syntax Description
Command Default
For Foreign Exchange Office (FXO), Foreign Exchange Station (FXS), and ear and mouth (E&M)
ports: decibels: 0 decibels
auto-dbm: -9 dBm
Command Modes
Voice-port configuration
Command History
Usage Guidelines
A system-wide loss plan must be implemented using both the input gain and output attenuation commands. You must consider other equipment (including PBXs) in the system when creating a loss plan. The default value for this command assumes that a standard transmission loss plan is in effect, meaning that there must be an attenuation of -6 dB between phones. Connections are implemented to provide -6 dB of attenuation when the input gain and output attenuation commands are configured with the default value of 0 dB.
You cannot increase the gain of a signal to the public switched telephone network (PSTN), but you can decrease it. If the voice level is too high, you can decrease the volume by either decreasing the input gain or increasing the output attenuation.
You can increase the gain of a signal coming into the router. If the voice level is too low, you can increase the input gain by using the input gain command.
The auto-control keyword and auto-dbm argument are available on an ear and mouth (E&M) voice port only if the signal type for that port is Land Mobile Radio (LMR). The auto-control keyword enables automatic gain control, which is performed by the digital signal processor (DSP). Automatic gain control adjusts speech to a comfortable volume when it becomes too loud or too soft. Because of radio network loss and other environmental factors, the speech level arriving at a router from an LMR system could be very low. You can use automatic gain control to ensure that the speech is played back at a more comfortable level. Because the gain is inserted digitally, the background noise can also be amplified. Automatic gain control is implemented as follows:
•
Output level: -9 dB
•Gain range: -12 dB to 20 dB
•Attack time (low to high): 30 milliseconds
•Attack time (high to low): 8 seconds
Examples
On the Cisco 3600 series router, the following example configures a 3-dB loss to be inserted at the transmit side of the interface:
voice-port 1/0/0
output attenuation 3
On the Cisco 3600 series router, the following example configures a 3-dB gain to be inserted at the transmit side of the interface:
voice-port 1/0/0
output attenuation -3
On the Cisco AS5300, the following example configures a 3-dB loss to be inserted at the transmit side of the interface:
voice-port 0:D
output attenuation 3
