auto-cut-through
To enable call completion when a PBX does not provide an M-lead response, use the auto-cut-through voice-port configuration command. Use the no form of this command to disable the auto-cut-through operation.
auto-cut-through
no auto-cut-throughSyntax Description
This command has no arguments or keywords.
Defaults
Auto-cut-through is enabled.
Command Mode
Voice-port configuration
Command History
11.3 MA
This command was introduced on the Cisco MC3810.
12.0(7)XK
This command was first supported on the Cisco 2600 and 3600 series routers.
Usage Guidelines
The auto-cut-through command applies to E&M voice ports only.
Examples
The following example enables call completion on a Cisco MC3810 when a PBX does not provide an M-lead response:
router(config)# voice-port 1/1router(config-voiceport)# auto-cut-throughThe following example enables call completion on a Cisco 2600 or 3600 when a PBX does not provide an M-lead response:
router(config)# voice-port 1/0/0router(config-voiceport)# auto-cut-throughRelated Commands
battery-reversal
To specify battery polarity reversal on an FXO or FXS port, use the battery-reversal voice-port configuration command. Use the no form of this command to disable battery reversal.
battery-reversal
no battery-reversalSyntax Description
This command has no arguments or keywords.
Defaults
Battery reversal is enabled.
Command Mode
Voice-port configuration
Command History
Usage Guidelines
The battery-reversal command applies to FXO and FXS voice ports. On Cisco 2600 and 3600 series routers, only analog voice ports in VIC-2FXO-M1 and VIC-2FXO-M2 voice interface cards are able to detect battery reversal; analog voice ports in VIC-2FXO and VIC-2FXO-EU voice interface cards do not detect battery reversal. On digital voice ports, battery reversal is only supported on E1 MELCAS; it is not supported in T1 channel associated signaling (CAS) or E1 CAS.
FXS ports normally reverse battery upon call connection. If an FXS port is connected to an FXO port that does not support battery reversal detection, you can use the no battery-reversal command on the FXS port to prevent unexpected behavior.
FXO ports in loopstart mode normally disconnect calls when they detect a second battery reversal (back to normal). You can use the no battery-reversal command on FXO ports to disable this action.
The battery-reversal command restores voice ports to their default battery-reversal operation.
Examples
The following example disables battery reversal on voice port 1/1 on a Cisco MC3810:
router(config)# voice-port 1/1router(config-voiceport)# no battery-reversalThe following example disables battery reversal on voice port 1/0/0 on a Cisco 2600 or 3600 series router:
router(config)# voice-port 1/0/0router(config-voiceport)# no battery-reversalRelated Commands
ccs connect
To configure a CCS connection on an interface configured to support CCS frame forwarding, use the ccs connect interface configuration command. To disable the CCS connection on the interface, use the no form of this command.
ccs connect {serial | atm} number [ dlci | pvc vpi/vci | pvc name ] [ cidnumber ]
no ccs connect {serial | atm} number [ dlci | pvc vpi/vci | pvc name ] [ cidnumber ]Syntax Description
The following parameters are used for Frame Relay configuration:
The following parameters are used for ATM configuration:
Defaults
No CCS connection is made.
Command Mode
Serial interface configuration mode
Command History
12.0(2)T
This command was introduced for the Cisco MC3810.
12.0(7)XK
Added CID syntax, removed dlci keyword and vcd options.
Usage Guidelines
Use this command to configure a CCS connection. If the CCS connection is over Frame Relay, specify a serial interface and the DLCI. If the CCS connection is over ATM, specify atm, the interface number (0 only on the Cisco MC3810), and the PVC.
If you have executed the ccs encap frf11 command, the cidnumber option allows you to specify any CID from 5 to 255. If you do not issue the ccs encap frf11 command, Cisco encapsulation is used, and any CID value other than 254 is ignored.
Note
Examples
To configure a frame relay CCS frame-forwarding connection on DLCI 100 by using the default CID of 254, enter the following command:
ccs connect serial 1 100or:
ccs connect serial 1 100 10To configure a CCS frame-forwarding connection over an ATM PVC, enter the following command:
ccs connect atm0 pvc 100/10or:
ccs connect atm0 pvc 10/100 21or:
ccs connect atm0 pvc mypvc_10 21To configure a Frame Relay CCS frame-forwarding connection on DLCI 100 using a CID of 110, enter the following command:
ccs connect serial 1 100 110Related Commands
ccs encap frf11
To configure the common channel signaling (CCS) packet encapsulation format for FRF.11, use the ccs encap frf11 command. Use the no form of this command to disable ccs encapsulation for FRF11.
ccs encap frf11
no ccs encap frf11
Syntax Description
There are no keywords or arguments.
Defaults
By default, the format is a Cisco packet format, using a channel ID (CID) of 254.
Command Mode
Serial configuration mode
Command History
Usage Guidelines
This command allows the specification of the standard Annex-C format. Use this command to define the packet format for the CCS packet; it places the FRF.11 Annex-C (Data Transfer Syntax) standard header on the CCS packets only.
Once the ccs encap frf11 command is executed, you can use the ccs connect command to specify a CID other than 254.
Examples
The following example shows how to configure a serial interface for Frame Relay:
router(config)# interface Serial1:15router(config-if)# ccs encap frf11router(config-if)# ccs connect Serial0 990 100Related Commands
codec (dial-peer)
To specify the voice codec for a network dial peer, enter the codec dial-peer configuration command. Use the no form of this command to restore the default value.
codec {g711alaw | g711ulaw | g723ar53 | g723ar63 | g723r53 | g723r63 | g726r16 | g726r24 | g726r32 | g728 | g729abr8 | g729ar8 | g729br8 | g729r8}[bytes payload-size]
no codecSyntax Description
Defaults
Dial peers are configured for g729r8.
Command Mode
Dial-peer configuration
Command History
Usage Guidelines
A codec type can be configured on the dial-peer if it is supported under the codec complexity setting you have specified.
The 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, g711alaw and g711ulaw provide higher-quality voice transmission than other codecs. For almost toll quality (and a significant savings in bandwidth), g729r8 provides near-toll quality with considerable bandwidth savings.
If the destination router does not support a codec required by the originating router, the call setup fails.
You can change the payload of each voice packet frame by using the bytes payload-size setting. However, increasing the payload size can add processing delay for each voice packet. Table 1 describes the voice payload options and default values for the codecs and packet voice protocols.
Example
The following example configures VoIP dial peer number 10 to use codec type g723r53 (G.723.1 at 5300 bps):
router(config)# dial-peer voice 10 voip router(config-dialpeer)# codec g723r53Related Commands
codec complexity
This voice-card configuration command sets codec complexity and call density.
show dial-peer voice
Displays the codec setting for dial peers.
codec (voice-port)
The codec voice-port configuration command on the Cisco MC3810 is no longer supported beginning in this release. This command was first supported in Cisco IOS Release 11.3(1)MA. Configure the codec value using the codec dial-peer configuration command.
codec complexity
To match the DSP complexity packaging to the codec(s) to be supported, enter the codec complexity voice-card configuration command. The no form of the command restores the default value.
codec complexity {high | medium}
no codec complexitySyntax Description
Defaults
The default is medium complexity.
Command Mode
Voice-card configuration
Command History
Usage Guidelines
Select a higher codec complexity if that is required in order to support a particular codec or combination of codecs.
Select a lower codec complexity to support the greatest number of voice channels, provided that the lower complexity is compatible with the particular codecs in use.
To change codec complexity, all of the DSP voice channels must be in the idle state.
Codec complexity refers to the amount of processing required to perform voice compression. Codec complexity affects the call density—the number of calls that can take place on the digital signal processors (DSPs). With higher codec complexity, fewer calls can be handled.
Note
Examples
The following example sets the codec complexity to high on a Cisco MC3810 containing one or two HCMs:
router(config)# voice-card 0 router(config-voicecard)# codec complexity highThe following example sets the codec complexity to high on voice card 1 in a Cisco 2600 or 3600 router:
router(config)# voice-card 1 router(config-voicecard)# codec complexity highRelated Command
condition
To manipulate the signaling format bit-pattern for all voice signaling types, use the condition command. Use the no form of this command to turn off conditioning on the voice port.
condition {tx-a-bit | tx-b-bit | tx-c-bit | tx-d-bit} {rx-a-bit | rx-b-bit | rx-c-bit | rx-d-bit} {on | off | invert}
no condition {tx-a-bit | tx-b-bit | tx-c-bit | tx-d-bit} {rx-a-bit | rx-b-bit | rx-c-bit | rx-d-bit} {on | off | invert}Syntax Description
Defaults
The signaling format is not manipulated (for all transmit or receive A, B, C, and D bits).
Command Mode
Voice-port configuration
Command History
11.3 MA
This command was introduced on the Cisco MC3810.
12.0(7)XK
This command was first supported on the Cisco 2600 and 3600 series routers.
Usage Guidelines
Use the condition command to manipulate the sent or received bit patterns to match expected patterns on a connected device. Be careful not to destroy the information content of the bit pattern. For example, forcing the A-bit on or off will prevent FXO interfaces from being able to generate both an on-hook and off-hook state.
Examples
The following example manipulates the signaling format bit-pattern on voice port 1/1 on a Cisco MC3810:
router(config)# voice-port 1/1router(config-voiceport)# condition tx-a-bit invertrouter(config-voiceport)# condition rx-a-bit invertThe following example manipulates the signaling format bit-pattern on voice port 1/1/2 on a Cisco 2600 or 3600:
router(config)# voice-port 1/0/0router(config-voiceport)# condition tx-a-bit invertrouter(config-voiceport)# condition rx-a-bit invertRelated Commands
Defines the transmit and receive bits for E&M and E&M MELCAS voice signaling.
Configures the E&M or E&M MELCAS voice port to ignore specific receive bits.
connect
This command was added in Cisco IOS Release 12.0(2)T on the Cisco MC3810. Beginning with Cisco IOS Release 12.0(7)XK, this command is no longer supported.
connect voice
This command was added in Cisco IOS Release 12.0(2)T on the Cisco MC3810. Beginning with Cisco IOS Release 12.0(7)XK, this command is no longer supported.
connection
To specify a connection mode for a voice port, use the connection voice-port configuration command. Use the no form of this command to disable the selected connection mode.
connection {plar | tie-line | plar-opx} digits | {trunk digits [answer-mode]}
no connection {plar | tie-line | plar-opx} digits | {trunk digits [answer-mode]}Syntax Description
Defaults
No connection mode is specified.
Command Mode
Voice-port configuration
Command History
Usage Guidelines
Use this 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 incoming calls over this connection. The destination peer is determined by the called number.
Use the connection trunk command to specify a permanent, "nailed up" tie-line connection to a PBX. You can use the connection trunk command for E&M-to-E&M trunks, FXO-to-FXS trunks, and FXS-to-FXS trunks. Signaling will be transported for E&M-to-E&M trunks and FXO-to-FXS trunks; signaling will not be transported for FXS-to-FXS trunks.
To configure one of the devices in the trunk connection to act as slave and only receive calls, use the answer-mode option with the connection trunk command when configuring that device.
Note
Use the connection tie-line command when the dial plan requires that additional digits be added in front of any digits dialed by the PBX, and that the combined set of digits be used to route the call onto the network. The operation is similar to the connection plar command operation, but in this case the tie-line port waits to collect digits from the PBX. The tie-line digits are 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 a Cisco 3600, with a destination telephone number of 555-9262:
router(config)# voice-port 1/0/0router(config-voiceport)# connection trunk 5559262The following example selects tie-line as the connection mode on a Cisco MC3810, with a destination telephone number of 555-9262:
router(config)# voice-port 1/1router(config-voiceport)# connection tie-line 5559262The following example specifies a PLAR off-premises extension connection on a Cisco 3600, with a destination telephone number of 555-9262:
router(config)# voice-port 1/0/0router(config-voiceport)# connection plar-opx 5559262The following example configures a Cisco 3600 series router for a trunk connection and specifies that it will establish the trunk only when it receives an incoming call:
router(config)# voice-port 1/0/0router(config-voiceport)# connection trunk 5559262 answer-modeRelated Commands
define
To define the transmit and receive bits for E&M and E&M Mercury Exchange Limited (MELCAS) voice signaling, use the define voice-port configuration command. Use the no form of this command to restore the default value.

dial-peer hunt
To specify a hunt selection order for dial-peers, use the dial-peer hunt dial-peer configuration command. Use the no form of this command to restore the default selection order.
dial-peer hunt hunt-order-number
no dial-peer huntSyntax Description
Defaults
The default is the longest match in phone number, explicit preference, and random selection (hunt order number 0).
Command Mode
Global configuration
Command History
12.0(7)XK
This command was introduced, and was first supported on the Cisco 2600 and 3600 series routers and on the Cisco MC3810 multiservice access concentrator.
Usage Guidelines
Use the dial-peer hunt dial-peer configuration command if you have configured hunt groups. "Longest match in phone number" refers to the destination pattern that matches the greatest number of the dialed digits. "Explicit preference" refers to the preference setting in the dial-peer configuration. "Least recent use" refers to the destination pattern that has waited the longest since being selected. "Random selection" weighs all of the destination patterns equally in a random selection mode.
Example
The following example configures the dial peers to hunt in the following order: (1) longest match in phone number, (2) explicit preference, (3) random selection.

Command Mode
Global configuration
Command History
12.0
This command was introduced.
12.0(7)XK
Usage was restricted to variable-length dialed numbers.
Usage Guidelines
There are certain areas in the world, 0for example, in certain European countries, where telephone numbers can vary in length. When a dialed-number string is identified as a variable length dialed-number, the system does not place a call until the configured value for the timeouts interdigits command has expired, or until the caller dials the terminating character. Use the dial-peer terminator global configuration command to change the terminating character.
Example
The following example specifies "9" as the terminating character for variable-length dialed numbers:
router# configure terminalrouter(config)# dial-peer terminator 9#Related Commands

encapsulation
To configure the ATM adaptation layer (AAL) and encapsulation type for an ATM PVC class, use the encapsulation command in the appropriate command mode. Use the no form of this command to remove an encapsulation from a PVC class.
encapsulation aal-encap
no encapsulation aal-encap
Note
Syntax Description
Defaults
The global default encapsulation is aal5snap. See the "Usage Guidelines" section for other default characteristics.
Command Mode
Interface-ATM-VC configuration (for an ATM PVC or SVC)
Command History
Usage Guidelines
Use one of the aal5mux encapsulation options to dedicate the specified PVC to a single protocol; use the aal5snap encapsulation option to multiplex two or more protocols over the same PVC. Whether you select aal5mux or aal5snap encapsulation depends on practical considerations, such as the type of network and the pricing offered by the network. If the network's pricing depends on the number of PVCs set up, aal5snap may be the appropriate choice. If pricing depends on the number of bytes transmitted, aal5mux may be the appropriate choice because it has slightly less overhead.
If you specify virtual template parameters after the ATM PVC is configured, issue a shutdown command followed by a no shutdown command on the ATM subinterface to restart the interface, causing the newly configured parameters (such as an IP address) to take effect.
Example
The following example configures a PVC to support encapsulation for Voice over ATM:
router(config-if)# pvc 20router(config-if-atm-pvc)# encapsulation aal5mux voiceencapsulation ftc-trunk
This command was added in Cisco IOS Release 12.0(2)T on the Cisco MC3810. Beginning with Cisco IOS Release 12.0(7)XK, this command is no longer supported.
forward-digits
To specify which digits to forward for voice calls, use the forward-digits dial-peer configuration command. If the no form of this command is entered, any digits not matching the destination-pattern are not forwarded. Use the default form of this command to restore the default state.
forward-digits {num-digit | all | extra}
no forward-digits
default forward-digitsSyntax Description
Defaults
Dialed digits not matching the destination-pattern are forwarded.
Command Mode
Dial-peer configuration
Command History
Usage Guidelines
This command applies only to POTS dial peers.
Forwarded digits are always right-justified, so that extra leading digits are stripped.
The destination pattern includes both explicit digits and wildcards if present.
Use the default form of this command if a non-default digit-forwarding scheme was entered previously and you wish to restore the default.
For QSIG ISDN connections, entering forward-digits all implies that all the digits of the called party number are sent to the ISDN connection. When you enter forward-digits num-digit and enter a number from 1 to 32, the number of digits specified (right justified) of the called part number are sent to the ISDN connection.
Examples
The following example forwards all of the digits in the destination pattern of a POTS dial peer:
router(config)# dial-peer voice 1 pots router(config-dial-peer)# destination-pattern 8... router(config-dial-peer)# forward-digits allThe following example forwards 4 of the digits in the destination pattern of a POTS dial peer:
router(config)# dial-peer voice 1 pots router(config-dial-peer)# destination-pattern 555.... router(config-dial-peer)# forward-digits 4The following example forwards the extra right-justified digits that exceed the length of the destination pattern of a POTS dial peer:

Command History
11.3NA
This command was introduced on the Cisco AS5800 platform.
12.0(7)XK
This command was first supported on the Cisco MC3810 platform.
Usage Guidelines
When the Cisco MC3810 is handling both modem and voice calls, it needs to be able to identify the service type of the call—meaning whether the incoming call to the server is a modem or a voice call. When the access server handles only modem calls, the service type identification is handled through modem pools. Modem pools associate calls with modem resources based on the called number (DNIS). In a mixed environment, where the server receives both modem and voice calls, you need to identify the service type of a call by using the incoming called-number command.
If you do not use the incoming called-number command, the server attempts to resolve whether an incoming call is a modem or voice call based on the interface over which the call comes. If the call comes in over an interface associated with a modem pool, the call is assumed to be a modem call; if a call comes in over a voice port associated with a dial peer, the call is assumed to be a voice call.
By default, there is no called number associated with the dial peer, which means that incoming calls will be associated with dial peers based on matching calling number with answer address, call number with destination pattern, or calling interface with configured interface.
This command applies to both VoIP and POTS dial peers.
Example
The following example configures calls coming in to the server with a called number of "3799262" as voice calls:
dial peer voice 10 potsincoming called-number 3799262isdn contiguous-bchan
To configure contiguous bearer channel handling on an E1 Primary Rate Interface (PRI) interface, use the isdn contiguous-bchan interface configuration command. To disable the contiguous B channel handling, use the no form of this command.
isdn contiguous-bchan
no isdn contiguous-bchan
Syntax Description
This command has no arguments or keywords.
Defaults
By default, contiguous B channel handling is off.
Command Mode
Interface configuration
Command History
Usage Guidelines
Use the isdn contiguous-bchan command to specify contiguous bearer channel handling so that B channels 1 through 30, skipping 16, map to timeslots 1 through 31). This is available for E1 PRI interfaces only, when the primary-qsig switch type option is configured by using the isdn switch-type command.
Example
The following example shows the command configuration on a Cisco 3660 series router E1 interface:
interface Serial5/0:15no ip addressip mroute-cacheno logging event link-statusisdn switch-type primary-qsigisdn overlap-receivingisdn incoming-voice voiceisdn continguous-bchanRelated Commands
isdn switch-type primary-qsig
In global or interface configuration mode, configures the primary-qsig switch type for PRI support.
isdn incoming-voice
To route all incoming voice calls as voice calls, to route them the modem and treat them as analog data, or to ensure that calls bypass the modems and are treated as digital data, use the isdn incoming-voice interface configuration command. Use the no form of this command to disable the setting.
isdn incoming-voice {data [56 | 64] | modem [56 | 64] | voice}
no isdn incoming-voice {data [56 | 64] | modem [56 | 64] | voice}
Syntax Description
Defaults
When a PRI or BRI interface is created, isdn incoming-voice voice is the default, except on a Cisco 2600 or 3600 BRI S/T TE interface. In this case, if the command is not specified, the default isdn incoming-voice modem configuration setting is converted to isdn incoming-voice voice when the interface receives an incoming call.

Command History
11.1
This command was introduced.
12.0(2)XC and 12.0(3)T
This command was made available for BRI interfaces.
12.0(7)XK
This command was modified to include the voice keyword.
Usage Guidelines
Unless you specify otherwise, all calls received by the router and characterized as voice calls are treated as such and not handled as digital data or not passed over to the modem.
On a Cisco 2600 or 3600 series router BRI S/T TE interface where the isdn incoming-voice command is not specified, the default isdn incoming-voice modem configuration setting is converted to isdn incoming-voice voice when the interface receives an incoming call.
To establish speedier connections for analog calls to the router, use the isdn incoming-voice command with the modem keyword to have voice calls routed through digital modems (as pulse-code modulated analog data) instead of being treated as digital data.
Example
The following example shows the command configuration on a Cisco 3660 series router T1 PRI interface:
interface Serial5/0:23no ip addressip mroute-cacheno logging event link-statusisdn switch-type primary-qsigisdn overlap-receivingisdn incoming-voice voiceisdn protocol-emulate

Command History
11.3 MA
This command was introduced for the Cisco MC3810.
12.0(7)XK
This command was first supported on the Cisco 2600 and 3600 series routers.
Usage Guidelines
This command applies to Voice over Frame Relay, Voice over ATM, and Voice over IP.
This command shows call-processing and protocol state-machine information for a voice port, if it is available. It also shows information on the DSP channel associated with the voice port, if it is available. All real-time information in the DSP channel, such as jitter and buffer overrun for example, is queried to the DSP channel, and asynchronous responses are returned to the host side.
If no call is active on a voice port, the show voice call summary command displays only the VPM (shutdown) state. If a call is active on a voice port, the VTSPS state is shown. For an on-net call or a local call without local-bypass (not cross-connected), the CODEC and VAD fields are displayed. For an off-net call or a local call with local-bypass, the CODEC and VAD fields are not displayed.
CODEC and VAD are not displayed in the show voice call port command, because this information is in the summary display.
This command provides the status at these levels of the call handling module:

Command History
12.0(3)XG and 12.0(4)T
This command was introduced on the Cisco MC3810.
12.0(7)XK
Default signaling patterns were defined.
Usage Guidelines
This command defines the signaling patterns that are used to identify the idle and OOS states.
Before configuring the signaling 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. After you finish defining the voice class, you will assign it to a dial peer.
To suppress voice packets whenever the transmit or receive trunk is in the idle state, use the idle receive and idle transmit commands in conjunction with the signal timing idle suppress-voice command.
To define the signaling bit patterns to be sent to the PBX when the trunk is out of service, use the idle receive and oos receive commands.
The oos receive pattern is the pattern sent to the PBX to indicate that the network trunk is out of service. The oos receive pattern is not used for pattern matching against the signaling packets received from the network.
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 expires and no signaling packets have been received, the router will send the idle receive and/or oos receive pattern to the PBX, depending on which pattern is specified by the signal sequence oos command.
Use the busy seized pattern only if the PBX does not have a pattern specifically intended to indicate an OOS state. If the PBX has a specific OOS pattern, use that pattern instead.
Examples
The following example restores default signaling bit patterns for the receive and transmit idle states:

Usage Guidelines
Before configuring the idle or OOS signal patterns to be sent, 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. After you finish defining the voice class, you will assign it to a dial peer.
Use this command to specify which signaling pattern(s) to send. Use the signal pattern idle receive or the signal pattern oos receive command to define the bit patterns of the signaling patterns if other than the defaults.
Examples
The following example defines voice class 10, sets the signal sequence oos to send only the idle signal pattern to the PBX, and applies the voice class configuration to VoFR dial peer 100.

signal timing idle suppress-voice
To specify the length of time before the router stops sending voice packets after a trunk goes into the idle state (no call in progress), use the signal timing idle suppress-voice voice-class configuration command. Use the no form of this command to restore the default value.
signal timing idle suppress-voice seconds
no signal timing idle suppress-voiceSyntax Description
seconds

Command History
12.0(3)XG
This command was introduced on the Cisco MC3810.
12.0(7)XK
This command was modified to simplify the configuration process.
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. After you finish defining the voice class, you will assign it 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. When the router or concentrator stops sending voice packets after the specified time, signaling packets continue to be sent.
To detect an idle trunk state, the router or concentrator monitors both transmit and receive signaling for the idle transmit and idle receive signaling patterns. These can be configured by the signal pattern idle transmit or signal pattern idle receive command, or they can be the defaults. The default idle receive pattern is the idle pattern of the local voice port. The default idle transmit pattern is the idle pattern of the far-end voice port.
Examples
The following example defines voice class 10, sets the idle detection time to 5 seconds, configures the trunk to use the default transmit and receive idle signal patterns, and applies the voice class configuration to VoFR dial peer 100.
