CCM 4.2.3 - MGCP - BRI Backhaul

Unanswered Question

Hello everybody,


Did anyone meet the following problem ?


I have a CCM 4.2.3 with a 2801 MGCP gateway.

BRI Backhaul is ok when the IOS version is 12.4.4.XC3, but it doesn't work anymore, once I had upgraded the gateway IOS version to 12.4.10


I had to change my protocol from MGCP to H323 to make it work.


Does anyone have a workaround to make BRI backhaul work with an 12.4.10 IPVOICE IOS gateway.


Thank you very much


Pascal

Hi,

you obviously need feature "MGCP Controlled Backhaul of BRI Signaling", "This feature enables MGCP controlled backhaul of BRI signaling using the NM-HD, NM-HDV2, EVM-HD and 2800/3800 with a BRI HWIC interface. Operation is in conjunction with Cisco CallManager." Cisco Software Advisor tool says that this feature is available in 12.4XE, 12.4XC, 12.4XA and 12.4T sw version trains, but not in 12.4 train.

I got the same problem on 2821.
