capabilities of your endpoints and the endpoints codec priority list.<br>
<br>
CCM has a service parameter where CCM will strip g729b thus preventing it from
being used in your network. I usually turn this parameter on during
installs to prevent the use of silence suppression. <br>
<br>
Look for ccm service parameter "strip g729 annex B"<br>
