Hi,

I am facing an issue where CCM user dials CME phone, the phone rings and caller gets ring back correctly but when called party (CME phone) answers the call, caller still gets two ring-backs and call get disconnected.


Call flow:


IP Phone --CCM--H.323--IP Leg--CME--IP Phone


Call works fine from CME phone to CCM phone.


I've captured config of H.323 GW ad CME box and output of debug voice ccapi inout from both boxes where:

calling no: 2122221003 (ext 1003)

called no: 12122221111.


Any thoughts on how to troubleshoot are very welcome.


Thanks,

inner_silence

It may be because of codec mismatch and may not have any transcoding resources.
