Support for QSIG Over BRI and Q.931 Over BRI Backhaul
Feature Overview
2
Cisco MGC Software Release 9.5(2)
Feature Overview
This feature provides support on the Cisco Media Gateway Controller (MGC) for QSIG over BRI and
Q.931 over BRI backhauling. This feature supports two BRI protocols, QSIG and Q.931. The
Cisco MGC can now backhaul layer 3 QSIG/Q.931 messages over a TCP session. TCP is required for
internetworking with BRI voice gateways.
Benefits
This feature provides the benefit described below.
Expansion of User Application
With the addition of support for QSIG over BRI and Q.931 over BRI backhauling, the Cisco MGC can
now be used to control calls for BRI voice gateways connected to QSIG private branch exchanges
(PBXs). This adds to the existing functionality that enables the Cisco MGC to control calls for Primary
Rate Interface (PRI) voice gateways connected to QSIG PBXs.
Restrictions
Enabling this feature provides a data pathway for the backhaul of QSIG/Q.931 messages from a
Cisco BRI voice gateway to the MGC. An MGCP data pathway must also be defined between the
Cisco BRI voice gateway and the MGC to form a complete duplex data pathway.
This feature can be used only with the following Cisco BRI voice gateways:
• Cisco 1751
• Cisco 1760
• Cisco 2600
• Cisco 2610XM
• Cisco 2611XM
• Cisco 2620XM
• Cisco 2621XM
• Cisco 2650XM
• Cisco 2651XM
• Cisco 2691
• Cisco 3640
• Cisco 3640A
• Cisco 3660
• Cisco 3725
• Cisco 3745
