color:#1F497D'>Sounds like a router or VPN device somewhere is queueing some
RTP. It will take some investigation to figure out where its queueing though. I
would start with getting a full list of L3 hops from the VPN user’s computer to
the phone you are testing with. And then start getting some packet captures
from both sides and see what they look like. They you can start moving the
captures inward in the topology and see which device is doing it. If it turns
out to be the Internets, then you might be SOL. But there is a possibility you
are missing some QOS somewhere that is just causing it to queue the RTP. This
is why RTP requires express forwarding (EF) so that it doesn’t get queued.<o:p></o:p></span></p>

<p class=MsoNormal>User calls because she is having soft phone issues.
Leave us a VM. for about 25 seconds the vm is normal speed.
Then the last few seconds are condensed into 1 sec.<o:p></o:p></p>

<p class=MsoNormal>Seems like maybe there is some kind of software on her box
that is storing and forwarding packets. Anyone else ever see this?<o:p></o:p></p>
