![]() Configure a Media Resource Group List and Media Resource Group List for each Location/Device Pool containing the previously configured Hardware TranscodersĢ. ![]() ![]() Configure a Hardware transcoder for each Location/Device Pool using the hardware DSPs located in the local voice gateway from each locationĢ. I found that somebody on the forum posted the same issue but in regard to the Transfer functionality of an IP Phone with call recording configured (the problem was caused by the codec mismatch).Īfter seeing that nobody replyed to my post I tried to redo the configuration again, more carefully this time.ġ. I tried allocating the software MTPs as well as hardware ones provided by some DSP modules on local voice gateways. It tries to allocate transcoding resources but it does not succeed. The PROBLEM is that if the codec negotiated between Phone A and Phone B is different than the codec negotiated between Phone B and the SIP trunk to the recording server, Phone B does not send any audio streams to the recording server.Īfter continuous testing we found that if the codecs are the same the stream gets sent, otherwise it does not.Īfter viewing the trace files I saw that CUCM locks the codec negotiated between Phone A and Phone B, and after that it sees that the call between Phone B and the recording server requires a different codec. The streams to the recorder server are sent as soon as Phone B picks up.The codec between Phone A and Phone B is negotiated depending on the regions configured.Phone B has a call recording profile configured the SIP trunk to the CallRec server has a Device Pool asociated with it (therefore a Region with a codec).let's say we have Phone A calling Phone B.we have a CallManager 7.0 Cluster with a recording solution (CallRec from Zoom). ![]() I was wondering if anybody has encountered the following problem: ![]()
