[Freeswitch-users] Issues with rtp audio going in slow motion

[Joel White]

I will work on getting a sip trace.  I am seeing this happen when
monitoring the system.  The calls sound fine and then it sounds like the
audio slows to a crawl.  It does not appear to happen regularly and I have
seen it happen on individual calls and on conferences.

The conferences have external DIDs for outside participants.  The internal
extensions dial a 5 digit extension.
