Configuring DSP Bypass Options
This section describes how to control whether local calls bypass the DSP or go through the DSP. Local calls normally bypass the DSP to minimize use of system resources (the default). Use this procedure to direct local calls through the DSP or to restore the default (DSP bypass).
To enable the input gain and output attenuation functions on a router or concentrator, you must disable voice local bypass.
Disabling Voice Local Bypass
(Cisco MC3810 only) To pass local calls through the DSPs, enter the following commands beginning in global configuration mode. If local calls are processed through the DSPs, the DSPs provide ringback tone to the voice ports.
1
router(config)# no voice local-bypass
Configures local calls to be processed through the DSPs.
Enabling Voice Local Bypass
(Cisco MC3810 only) To restore the default configuration, in which local calls bypass the DSPs, enter the following commands beginning in global configuration mode:
1
router# configure terminal
Enter global configuration mode.
2
router(config)# voice local-bypass
Configures local calls to bypass the DSPs.

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
codec (voice-port)
The codec voice-port configuration command on the Cisco MC3810 is no longer supported beginning in this release. The command was first supported in Cisco IOS Release 11.3(1)MA. Configure the codec value using the codec dial-peer configuration 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.
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

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:

The waiting period in milliseconds before silence detection and suppression of voice-packet transmission.
The range is 250 to 65536. The default is 250.
Defaults
250 milliseconds
Command Mode
Global configuration
Command History
Usage Guidelines
This command affects all voice ports on a router or concentrator, but it does not affect calls already in progress.
You can use this command in transparent CCS applications in which you want VAD to activate when the voice channel is idle, but not during active calls. With a longer silence detection delay, VAD reacts to the silence of an idle voice channel, but not to pauses in conversation.
This command does not affect voice codecs that have ITU-standardized built-in VAD features—for example, G.729B, G.729AB, G.723.1A. The VAD behavior and parameters of these codecs are defined exclusively by the applicable ITU standard.
Examples
The following example configures a 20-second delay before VAD silence detection is enabled:

Use the debug vpm all command to enable the complete set of VPM debugging commands: debug vpm dsp, debug vpm error, debug vpm port, debug vpm spi, and debug vpm trunk_sc.
Execution of no debug all will turn off all port level debugging. It is usually a good idea to turn off all debugging and then enter the debug commands you are interested in one by one. This will help to avoid confusion about which ports you are actually debugging.
Examples
For sample outputs, refer to the individual commands in this chapter.

Command History
Usage Guidelines
Use this command to limit the debug output to a particular voice port. The debug output can be quite voluminous for a single channel. The entire vtsp debug output form a platform with 12 voice ports might create problems. Use this debug with any or all of the other debug modes.
Execution of no debug vtsp all will turn off all VTSP-level debugging. It is usually a good idea to turn off all debugging and then enter the debug commands you are interested in one by one. This will help to avoid confusion about which ports you are actually debugging.

debug vtsp stats
no debug vtsp statsSyntax Description
This command has no arguments or keywords.
Defaults
Debugging for vtsp stats is not enabled.
Command History
12.0(3)T
This command was introduced on the Cisco AS5300 platform.
12.0(7)XK
This command was first supported on the Cisco 2600, 3600 and MC3810 platforms.
Usage Guidelines
The debug vtsp stats command generates a collection of DSP statistics for generating RTCP packets and a collection of other statistical information.
Sample Display

debug vtsp vofr subframe
To display the first 10 bytes (including header) of selected VoFR subframes for the interface, use the debug vtsp vofr subframe command. Use the no form of the command to turn off the debug function.
debug vtsp vofr subframe payload [from-dsp] [to-dsp]
no debug vtsp vofr subframeSyntax Description
Defaults
Debugging for vtsp vofr subframe is not enabled.
Command History
12.0(3)XG, 12.0(4)T
This command was introduced on the Cisco 2600 and 3600 platforms.
12.0(7)XK
This command was first supported on the Cisco MC3810 platform.
Usage Guidelines
Each debug output displays the first 10 bytes of the FRF.11 subframe, including header bytes. The from-dsp and to-dsp options can be used to limit the debugs to a single direction. If not specified, debugs are displayed for subframes when they are received from the DSP and before they are sent to the DSP.
Use extreme caution in selecting payload options 0 and 6. These options may cause network instability.
Examples
The following example shows sample output from the debug vtsp vofr subframe command:
