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 can see the first packet sent to NAT in badnat.cap; packet number 984
according to wireshark.

Also, I have attached the console debug output log.  The excerpts above
are from said log.
