Summary:                    T.38 with devices behind NAT does not work
Description: 
I've found trouble described in
https://issues.asterisk.org/view.php?id=10417
There is patch for 1.4, but I have 1.6.2, so it does not work

Scenario is :
Host1 192.168.x.x (NAT IP 100.100.100.100) sends fax host2 200.200.200.200
but after re-invite t.38 session asterisk transmits udptl packets to
internal IP 192.168.x.x
