CCM 5.1 and h323 gateway

Hello all!

I need your help! I try to connect CCM and my h323 provider.


Call came from provider to my 2811 and should be translate to CCM, but - I can get call, but after 5 sec. connectons droped, no voice on both end. Why? How can I debug what is going on?

My second problem - no call route outside my network. I add h323 gateway, create route group/route list/route pattern, CCM trying to place call, but after 30-40 sec. i can't place a call. How can i see logs/debugs about WTF ig going on CCM? I can debug and trace everything on 2811, but how can i debug a call on CCM?

My 2811 config is:



voice service voip

allow-connections h323 to h323

fax protocol t38 ls-redundancy 0 hs-redundancy 0 fallback none





interface FastEthernet0/1

description ==C2811_CONNECT==
