Feature History
9.8(1)
The QSIG Tunneling over SIP feature is introduced in the Cisco PGW 2200 Softswitch software.
This document describes the QSIG Tunneling over SIP feature. This feature is described in the following sections:•
Supported Standards, MIBs, and RFCs
•
Feature Description
The Cisco Unified Communications Manager (CUCM) clusters are used to interwork directly by tunneling QSIG for callback scenarios. With this feature, interworking among CUCMs can be enhanced by tunneling QSIG over the Session Initiation Protocol (SIP) through PGW, which acts as a transit switch.
The QSIG Tunneling over SIP feature provides a new interface for QSIG Tunneling over SIP protocol in PGW for callback scenarios. This feature enables transparent interworking between Call Managers by tunneling the QSIG information in the SIP messages.
Applying this feature, PGW will interwork with the Call Managers (single-cluster or multiple-cluster configurations) on SIP interfaces as a transit switch.
Benefits
This feature provides the following benefit:
Enables transparent interworking between Call Managers by tunneling the QSIG information in the SIP messages in callback scenarios.

Provisioning Tasks
Two properties are introduced in the QSIG Tunneling over SIP feature:
•
•
SIPQSupport enables or disables the support of the QSIG Tunneling over SIP feature, while SIPQnumberpreference enables the QSIG Tunneling over SIP feature to select call routing based on the called numbers present in the SIP or the QISG message. Perform the following tasks to add new properties:
•
profile:name="sip- prof",type="SIPPROFILE",custgrpid="xyz",mgcdomain="x.x.x.x", SIPQSupport = "1"
•
prov-add:profile:name="sip-prof1",type="SIPPROFILE",custgrpid="xyz",mgcdomain="x.x.x.x"
prov-ed:profile:name="SIPPROFILE",custgrpid="xyz",MGCdomain="x.x.x.x", SIPQnumberpreference = "1"
You can edit the new properties by performing the following steps:
•
prov-ed:profile:name="SIPPROFILE",custgrpid="xyz",MGCdomain="x.x.x.x", SIPQnumberpreference = "0"
•
prov-ed:profile:name=" sip- prof ",custgrpid="xyz",MGCdomain="x.x.x.x", SIPQSupport = "1"
