<p class="MsoNormal">To dumb this excellent discussion down a bit MediaManager is created when media negotiation has to happen between two call legs and this doesn't always happen at the same time one leg sends its media information. <o:p></o:p></p>

<p class="MsoNormal">The MXTimeout getting cancelled will be whenever we need to stop waiting for the media connection to be established. In general this happens when we have enough information from both call legs to proceed with establishing media or cancel
the call because there are no matching capabilities. It can also happen if one side disconnects the call during media negotiation (try H.323 over a satellite with slow-start and you'll see this a lot).<o:p></o:p></p>

be, is it safe to say the creation of a new MediaManager process is initiated by specific events during the call, received by the outbound call-leg, and vary from protocol to protocol? I’m aware it’s during the media connection attempt for two CIs, but I’m

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif"">Is there a specific CCM trace entry that corresponds to the moment where the Media Exchange Timeout timer is stopped? From what I understand, the timer begins when a new
MediaManager process is created for the AuConnect request, but there doesn’t seem to be any obvious moment when the timer is stopped during a successful media connection. Would it be at the “AuConnectInfo, audio, CI (xxxxxx, xxxxxx)”? The purpose of having
this would be to quickly identify the moment a successful media connection was established during situations where reviewing signaling transactions for media capabilities isn’t exactly required.<o:p></o:p></span></p>
