QSIG Support for Tcl IVR 2.0

Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Use Cisco Feature Navigator to find information about platform support and Cisco software image support. To access Cisco Feature Navigator, go to www.cisco.com/go/cfn. An account on Cisco.com is not required.

• Perform the prerequisites that are listed in the "Prerequisites for Configuring an ISDN Voice Interface" section.
• Establish a working IP network. For more information, see the Cisco IOS documentation set. See specifically the Cisco IOS IP and IP Routing Configuration Guide and the Cisco IOS Voice, Video, and Fax Configuration Guide.
• Configure VoIP. For more information, see the Cisco IOS Voice, Video, and Fax Configuration Guide.
• Download the Tcl scripts required for this feature from the following website: http://www.cisco.com/cgi-bin/tablebuild.pl/tclware
• Ensure that the VCWare version used for the Cisco AS5300 is compatible with the Cisco IOS image being used.

Note	VCWare applies only to the Cisco AS5300.

Before configuring IVR Version 2.0 features, do the following:

• Download the Tcl scripts and audio files to be used with this feature. Store them on a TFTP server configured to interact with your gateway access server.
• Create the IVR/Tcl application script to use when configuring IVR. Store it on a server or at a location where it can be retrieved by the gateway access server. Then configure the server to use IVR with the application that you created.
• Configure the dial peer on incoming POTS or VoIP dial peers.

Restrictions are described in the "Restrictions for Configuring ISDN Voice Interfaces". In addition, the following apply:

• This feature is applicable to only the following:
  • VoIP and POTS dial peers
  • Tcl IVR version 2.0 only; not version 1.0

Q.SIG support is required for European countries to interconnect enterprise customers to a wholesale voice solution. The Q.SIG for Tcl IVR 2.0 feature provides transparent Q.SIG interworking when using a Tcl IVR version 2.0 voice application on a Cisco IOS voice gateway. This functionality can be enabled using a new CLI on the POTS or VoIP dial-peer. Prior to this feature, Q.SIG messages were interpreted by the Tcl IVR 2.0 application, rather than passed transparently to the remote endpoint.

Note	General information about ISDN voice interfaces is presented in the "Information About ISDN Voice Interfaces" section.

• Configuring QSIG
• Configuring Supplementary Service for a POTS Dial Peer
• Configuring Supplementary Service for a VoIP Dial Peer
• Verifying QSIG and Supplementary Service

The following sample output is typical of that for implementation of supplementary service. ISDN supplementary service messages from PBX 1 are sent transparently to PBX 2 by routers 1 and 2 as if PBX 1 and PBX 2 were connected directly to each other.
