Configuring Call Waiting Tone Cadence

First Published: November 19, 2010

 

This module describes the Configurable Call Waiting Tone Cadence feature, a Skinny Client Control Protocol (SCCP) telephony control (STC) application (STCAPP) supplementary-service feature supported on an analog Foreign Exchange Station (FXS) voice port. This feature is supported for analog SCCP endpoints that are controlled by the Cisco Unified Communications Manager (Cisco Unified CM) only.

Restrictions for Configurable Call Waiting Tone Cadence

  • This feature is not supported in Cisco Unified CME.

Benefits of Configurable Call Waiting Tone Cadence

The Configurable Call Waiting Tone Cadence feature provides parity with incumbent time-division multiplexing switches.

It also provides backward compatibility, with the single-beep tone as default behavior, as long the existing configuration is not modified.

Information About Configurable Call Waiting Tone Cadence

To enable SCCP supplementary features on analog phones connected to FXS ports on a Cisco voice gateway, you should understand the following concepts:

Configurable Call Waiting Tone Cadence

For analog endpoints in Cisco Unified CM, the Configurable Call Waiting Tone Cadence enables the call waiting tone to be configured as a distinct ringtone played continuously on Cisco IOS SCCP voice gateways until the called party switches from the active call to an incoming call and the new caller has not hung up.

A configurable CLI allows you to choose the ring cadence to use for the call waiting tone.

If it is configured, the ringtone will periodically repeat with configured interval until either the user switches to the new call or the calling party hangs up.

The IOS managed timer is utilized to provide this functionality. A separate timer is used for each port but it is activated only when the call waiting tone is being played.

The value of 0 (the default for compatibility reasons) means that no repetition should occur.

The offhook caller ID is displayed only once if the repeative call waiting tone is configured.

How to Configure Call Waiting Tone Cadence

The “Configuring Call Waiting Tone Cadence” section provides detailed configuration information.

Configuration Examples for Configurable Call Waiting Tone Cadence

This section provides the following configuration example:

Example: Configurable Call Waiting Tone Cadence on a Cisco IOS Gateway

The following is a sample output from the show run command showing how to enable the Configurable Call Waiting Tone Cadence STCAPP supplementary-service feature for analog phones connected to port 2/4 on a Cisco VG224. A similar sample output can also be displayed using the show stcapp device voice-port x/x (or x/x/x) command.

Router(config)# show run
.
