<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#404040">Do you see a StartMediaTransmission being sent to your MOH server? Look for MohDControl for SCCP signals to the MOH server - one process instance is created per
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>
