QSIG Digit Forwarding on the
Cisco MC3810

Feature Overview

This feature extends support for dial-peer digit forwarding to ISDN PRI QSIG signaling calls on the Cisco MC3810.

Benefits

When ISDN PRI QSIG Signaling was first introduced on the Cisco MC3810 in Cisco IOS Release 12.0(2)T, digit forwarding on POTS dial peers was not supported in conjunction with ISDN PRI QSIG. In this release, digit forwarding is now supported in conjunction with ISDN PRI QSIG.

Related Documents

•For information on configuring ISDN PRI QSIG Signaling on the Cisco MC3810, refer to the ISDN PRI QSIG Voice Signaling online feature guide for 12.0(2)T.

•For information on digit forwarding as an option for POTS dial peers, refer to the chapter "Voice Dial Plan Considerations" in the Cisco MC3810 Multiservice Access Concentrator Software Configuration Guide.

Supported Platforms

This feature is supported only on the Cisco MC3810.

Prerequisites

ISDN PRI QSIG signaling must be configured.

Supported MIBs and RFCs

None.

Configuration Task

This procedure configures digit forwarding on the POTS dial peer. It assumes that the destination pattern and the port commands have already been assigned to the POTS dial peer. Digit forwarding is optional on the POTS dial peer.

To configure digit forwarding on the POTS dial peer, use the following commands:

Step
Command
Purpose

1 

Router(config)# dial peer voice number pots

Enter dial peer configuration mode for the POTS dial peer.

2 

Router(config-dialpeer)# forward digits {num-digits | 
all | implicit}

If using the forward-digits feature, configure the digit-forwarding method that will be used on the dial peer. The valid range for the number of digits forwarded (num-digit) is 0-32.

If you set the number of digits forwarded to 0, no digits are forwarded.


Verifying the Dial Peer Configuration

If you have relatively few dial peers configured, you can use the show dial-peer voice summary command to verify that the data configured is correct.

Configuration Example

The following example configures forward digits for a POTS dial peer on a Cisco MC3810: 

dial-peer voice 1 pots 
  destination-pattern 8... 
  forward-digits all

Command Reference

This section documents a modified command. All other commands used with this feature are documented in the Cisco IOS Release 12.0 and 12.0(2)T command references.

forward-digits

To configure forward digits for voice calls on the Cisco MC3810, use the forward-digits dial-peer configuration command. Use the no form of this command to restore the default value.

forward-digits {num-digit | all | implicit}
no forward-digits {num-digit | all | implicit}

Syntax Description

num-digit

The number of digits to be forwarded. If the number of digits is longer than the length of a destination phone number, the length of the destination number is used. The valid range is 0-32. Setting the value to 0 is equivalent to entering no forward digits (the default).

all

Forward all digits. If "all" is used, the full length of the destination pattern will be used.

implicit

Exactly matched digits are not forwarded. Only digits matched by the wildcard pattern are forwarded.


Default

No digits are forwarded.

Command Modes

Dial-peer configuration

Command History

Release
Modification

11.3(1)MA

This command was first introduced.

12.0(2)T

The implicit option was added.

12.0(4)T

This command was modified to support ISDN PRI QSIG signalling calls.


Usage Guidelines

This command applies only to the Cisco MC3810.

This command applies only to POTS dial peers.

Forwarded digits are always right-justified so that extra leading digits are stripped.

For QSIG ISDN connections, entering forward-digits all implies that all of the digits of the called party number are sent to the ISDN connection. When you enter forward-digits num-digit and enter a number between 1 and 32, the number of digits specified (right justified) of the called part number are sent to the ISDN connection. When you enter forward-digits implicit, then the number of matched digits matching the wildcard for the called party number are sent to the ISDN connection. For example, if the called part number is 51234, the digits being sent to the ISDN connection is 1234.

Example

The following example configures forward digits for a POTS dial peer on a Cisco MC3810: 

dial-peer voice 1 pots 
  destination-pattern 8... 
  forward-digits all
