I could be wrong but I think I've seen this before and determined it was caused by G.729b (G.729 with silence suppression) connections. <br><br>You could set the 'Strip G.729 Annex B (Silence Suppression) from Capabilities' service parameter to true and see if that makes a difference.
<br><br>If it happens on conference calls you could remove the codec g792abr8 and codec g729br8 commands from the dsp-farm profile on the gateway. <br><br><a class="itemLinkList" href="javascript: openHelpWindow('vendorconfighelp.asp?instance=xmldi://cisco.com/serviceParameters/0&title=Cisco+CallManager+Parameters+Help&showAll=No#StripSilenceSuppressionCapabilities');" name="StripSilenceSuppressionCapabilities">
