Support for QSIG Over BRI and Q.931 Over BRI Backhaul
Provisioning Tasks

Retrieving Data on Supported Signaling Protocols
You can retrieve protocol data for the current provisioning session. To do this, log in to the active
Cisco MGC, start an MML session, and enter the following command:
prov-rtrv:variants
Adding QSIG/Q.931 Over BRI Backhaul Connections
This section contains the procedures that you must perform to add QSIG/Q.931 over BRI backhaul
connections to your Cisco MGC provisioning data. When provisioning the components that enable the
Cisco MGC to support QSIG/Q.931 over BRI backhaul, perform the procedures in the following order:
• Ensuring Proper Cisco ISDN Voice Gateway Configuration, page 12
• Adding Cisco BRI Voice Gateway External Nodes, page 12
• Adding MGCP Signaling Services, page 14
• Adding QSIG/Q.931 Over BRI Backhaul Signaling Services, page 15
• Adding IP Routes (Optional), page 16
• Adding Backhaul TCP Links, page 17
• Adding MGCP IP Links, page 18
• Adding QSIG/Q.931 Over BRI Backhaul D-Channels, page 19
Ensuring Proper Cisco ISDN Voice Gateway Configuration
For this feature to work properly, the connected Cisco ISDN BRI voice gateway must be configured such
that the switchback function is disabled. This prevents the voice gateway from automatically
reconnecting with the active Cisco MGC. The switchback function is disabled using the following
command:
Gateway(config)#ccm-manager switchback never
Refer to the documentation for your voice gateway for more information.
Proceed to the “Adding Cisco BRI Voice Gateway External Nodes” section on page 12.
Adding Cisco BRI Voice Gateway External Nodes
Note If your network supports both PRI and BRI backhaul signaling, we recommend that you maintain the
PRI and BRI interfaces on different media gateways. PRI signaling backhaul configurations typically use
redundant links between the Cisco MGC and the media gateway, and BRI signaling backhaul
configurations use a single link between the Cisco MGC and the media gateway.
