Summary:                    Chan_skinny causing asterisk  dumps core randomly
Description: 
I have a 1.4.19 system that has 35 chan_skinny devices that is randomly
crashing on ast_rtp_new_source.

All of the phones are wireless 7920 or 7921.  It usually happens every
week or so, however, it's done it 3 times today.  Don't know if the problem
is with RTP, or chan_skinny.  

The backtrace looks the same every time.  Hopefully this is an easy fix.

Here's the backtrace.
