Feature Overview

The Dialing Number Enhancement feature removes previous restrictions on the number of dialed digits accepted as a valid telephone number in the Called Party number information element (IE) for the National or International numbering types.

Benefits

The Dialing Number Enhancement feature is a change to the Cisco IOS software that makes the ISDN dialing plan more flexible by allowing a range rather than a restricted number of digits to be accepted for dialing.

Restrictions

The Dialing Number Enhancement feature was developed for interfaces configured for network-side ISDN where the Called Party IE digits are of National or International numbering types.

Related Documents

Refer to the chapter "Configuring Network Side ISDN PRI Signaling, Trunking, and Switching" in the part "Signaling Configuration" in the Cisco IOS Dial Technologies Configuration Guide, Release 12.2, for more information about configuring network-side ISDN switches.

Supported Platforms

The Dialing Number Enhancement feature is supported on the Cisco AS530, Cisco AS5400, and Cisco AS5800 access servers.

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to quickly determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Configuration Tasks

No new commands are associated with the Dialing Number Enhancement feature. See the "Troubleshooting Tips" section for information about verifying numbering plans and switch types configured. See the "Configuration Examples" section for configuration examples.

Troubleshooting Tips

To learn and, if necessary, change the numbering plan and type currently configured on the ISDN interface, perform the following steps:

---

Step 1 To learn the numbering plan and type currently configured, use the debug isdn q931 command in EXEC mode:

Router# debug isdn q931

4w1d: ISDN Se0:23: TX ->  SETUP pd = 8  callref = 0x000D

4w1d:         Bearer Capability i = 0x8890

4w1d:         Channel ID i = 0xA98397

4w1d:         Called Party Number i = 0xA1, '12345', Plan:ISDN, Type:National

4w1d: ISDN Se0:23: RX <-  RELEASE_COMP pd = 8  callref = 0x800D

The Called Party Number report lists the numbering plan and type.

Step 2 To change the numbering plan and type, use the isdn map command in interface configuration mode. Use the command line interface help feature to list the choices.

Router(config-if)# isdn map address 78886 plan ?

  data         Data plan

  isdn         ISDN plan

  national     National plan

  privacy      Private plan

  reserved     Reserved extension

  .

  .

  .

  reserved/7   Reserved value 7

  telex        TELEX plan

  unknown      Unknown plan

Router(config-if)# isdn map address 78886 plan isdn type ?

  abbreviated    Abbreviated type

  international  International type

  national       National type

  network        Network type

  reserved       Reserved type

  reserved/5     Reserved value 5

  subscriber     Subscriber type

  unknown        Unknown type

Step 3 To force the ISDN numbering plan and National type on the peer (calling number) side, use the isdn map command with the following keywords in interface configuration mode:

Router(config-if)# isdn map address telephone-number plan isdn type national

Monitoring and Maintaining Dialing Number Enhancement

To monitor and maintain the Dialing Number Enhancement feature, use the procedure in the "Troubleshooting Tips" section.

You may also find the following EXEC command useful for displaying an extensive report about the ISDN interfaces, including the switch type and the status of ISDN Layers 1 through 3:

Command	Purpose
Router# show isdn status [interface-type number]	Displays the status of all ISDN interfaces, or just the specified interface.
