The following Cisco IOS VoIP feature is supported on the Cisco 1700 series platforms for Cisco IOS Release 12.3(4)XQ:

•MGCP-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager

MGCP-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager

The Media Gateway Control Protocol (MGCP)-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager feature provides MGCP service to remote-office media gateways that connect by means of ISDN BRI trunks to a centralized Cisco CallManager media gateway controller for the purpose of call processing. D-channel signal information is backhauled to the call manager through a TCP session.

If connection to the primary call manager fails, call processing reverts to a backup call manager until the connection to the primary call is restored. If connections to the primary call manager and all backup call managers fail, call processing reverts to H.323 on the media gateway. When a connection is restored, call processing reverts to the primary or other available call manager and to MGCP.

The MGCP-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager feature offers the following benefits:

•Centralized call-management architecture, enabling a high degree of network control

•Short voice cut-through times

•Graceful evolution to new technology and to Cisco Architecture for Voice, Video, and Integrated Data (AVVID)

---

Note Note The MGCP-Controlled Backhaul of BRI Signaling in Conjunction with Cisco CallManager feature requires Cisco CallManager 3.3(2) Feature Patch 1. Subsequent 3.3 feature patches will also support this feature. However, this feature is not yet supported in the mainline Cisco CallManager release. Feature patches are not posted to CCO and distribution is strictly controlled. Contact your Cisco account team for further information.
