Summary:                    some RTP packets sent to NAT IP instead of public
IP; breaks built-in jitterbuffer on some phones
Description: 
I am experiencing the same symptoms as
http://bugs.digium.com/view.php?id=0012566 but with 1.4.20-rc3, not
trunk.  The bug was fixed in trunk, but not in 1.4.x.

To reiterate the problem:

Phone 100 calls phone 102.  Phone 102 answers and starts counting "1 2 3 4
5".  Phone 100 doesn't hear anything until "3" or "4".

You will also notice that there is a gap between when the 200 OK answered
and when packets actually went to the phone you called from, because the
phone you placed a call to did not send any for a short period of time.
