[Freeswitch-users] Insufficient RTP stream

This is called RTP Auto Adjust
This occurs when the SDP of the other side sends FS the wrong media IP in
the SDP
If FS gets packets from some other place besides where it thinks its
supposed to send packets in a window of the first 10 packets repeatedly,
then it auto adjusts the destination, fixing the problem.  If you look at
your FreeSWITCH console when you make this call it's likely
you see a message about RTP auto adjusting the IP.
