MGCP problem with c881 voice

[Gilles Dellaccio]

Hi,

I want to use a cisco "881 voice" with my CUCM v9.1.

This router, have a mgcp configuration and it's "ok", but i can't configure the BRI and the FXS with the CUCM.

It's possible to use the 881 with mgcp and configure fxs and bri?

Thanks.

Hi,

it didn't work with mgcp, but with a trunk sip it's OK.

Yep, seems a problem MGCP and CUCM 9.1

So we are left with H323/SIP or upgrade CUCM to 10.5 which seems to solve the problems.

Thank you very much
