Description:If I have an extension which does Playback() of a file into a MeetMe or ConfBridge conference, the playback sound is stuttering or suddenly stopping randomly.

Capturing the RTP stream, there are no errors like lost or out of order packets, it's just silence packets.
If I talk on the SIP/somephone which I call on the other extension, the sound is played back and I can see it on the RTP stream.

I tried it with A* on more than one machine, of varying processing power.

Here's a sample dialplan which triggers the problem:

[default]

exten => 100,1,NoOp()
same => n,Page(SIP/101&SIP/102)
same => n,Hangup()

exten => 101,1,NoOp()
same => n,Dial(SIP/somephone)
same => n,Hangup()

exten => 102,1,NoOp()
same => n,Answer(100)
same => n,Playback(Somelongfile)
