Re: [Opalvoip-user] Unable to hear IVR - Opalmcu & IVR on eridani (Works on Luyten)

Quick comment:

The media stream starting is pretty redundant in execution. For a a 
source/sink pair only one side really needs to be started as all it does 
is start the common OpalMediaPatch between them. So, that is unlikely to 
be the problem.

Didn't I direct you toward a possibility with the jitter buffers? I 
don't have time to go back exploring through old mails, but I seem to 
remember there being something in that area that didn't look right. I 
think it was that a jitter buffer was in use for IVR <-> MCU which 
probably shouldn't happen. hard to know without detailed analysis.
