Customer with CUCM 10.5.2 trying to integrate with a NICE recording solution. Everything configured per NICE documentation and rechecked that several times with the NICE vendor. However, if calling to/from the PSTN or legacy Nortel PBX to a Cisco 78xx or IP Communicator soft phone - we get one-way audio pushed out the SIP trunk to the NICE system. If it's a Cisco to Cisco phone call - the audio is garbled.
Has anyone experienced this issue with this type of integration - or the same issue with a SIP trunk to the CUCM to another system at all? We're at a loss here.
