Restrictions for MGCP-Controlled Backhaul of BRI Signaling

*BRI backhaul uses the enhanced interface numbering support available in Cisco IOS Release 12.3(11)T and later. Previous releases supported only the slot/subslot/port format with the subslot forced to 0 on the Cisco 2600 series, Cisco 3600 series, and Cisco 3700 series. Cisco IOS Release 12.3(11)T and later releases support both the slot/port and slot/subslot/port interface numbering formats for BRI backhaul.


*Only the ETSI BRI Basic-NET3 switch type is supported.


*BRI calls are cleared during MGCP gateway fallback and rehome because ISDN BRI L2 must be reinitiated and brought up again by the new L3 task.


*Do not add the application mgcpapp command to voice dial peers that support BRI backhaul.

Hi Kevin,


I am using a 2811 with MGCP / BRI on a CM5 running IOS 12.4(9)T.


The setup on the router is very simple, and it seems to work ok, except, that caller id (both inbound and outbound) seems to be a problem at the moment.
