Summary:                    [patch][post 1.4] Don't change NATed address on
re-invites
Description: 
When SIP/H.323 endpoint located behind NAT, RTP will negotiate its real IP
address and port by listening for incoming RTP packets and remember this
address for sending data to this endpoint. When re-invite (native bridge)
is happens with such endpoint, endpoint will reports its address behind
NAT, and chan_sip will update RTP information with this address, what will
cause to re-invite for peer side. If peer side located behind NAT too this
will provide looping by permanent chaning of RTP addresses by one then
other side.

PCadach: I've gone over this many times, reread it a lot, and am extremely
hesitant with changing it until I see a SIP trace of the actual issue.
Until that time I'm suspending this.
