I am using UCCX and i have a problem when connect trunk to Telco. They use codec g711ulaw and g711alaw together. When call in, they send g711alaw codec and i have a problem with voice oneway. When i enable MTP on configuration trunk on CUCM. Voice 2 way ok. But i cant call out . When i disable MTP, i can call out but will have a issue voice oneway call in for codec. The telco cant change only one codec. When call out, CUCM will send codec g711ulaw. Can you help me ?
