experience but can happen. If set to detailed, you should see the StartMediaTransmission and StartMediaTransmissionACK being logged in the trace in addition to its ability or inability to allocate and play the selected MOH audio source file.

MOH server. But first, before sending the StartMediaTransmission signal to MohDControl, CCM will first attempt to get media information from the remote end, and I would first take a look at this call-leg and (at a high level) make sure the OLC/OLCack is exchanged
with no issues. What signaling protocol is being used on the opposite call-leg? If that exchange fails then you won’t see a StartMediaTransmission to MohDControl. If you do see a StartMediaTransmission to MohDControl then is it ACK’ing that signal?<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Thanks Ryan. The region relationships is fine as the MOH is in a special MOH region which is 64kbps to every other region, including the one in question. All traces indicate that the media caps are a match
at g711ulaw.<o:p></o:p></p>

<p class="MsoNormal">Another common source of this is codec mismatch. <br>
<br>
So if your ingress region isn't related to the region that MoH is in with the G.711/G.722 bandwidth profile, you'll get this issue. If you get tone-on-hold then it is usally partition/css/tftp related but dead silence is usually codec related.<br>
