Summary:                    Playback() on a meetme/confbridge stutters/drops
randomly
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)
