[Freeswitch-users] Sofia - calling through gateway - duplicate RTP port in SDP

[Anthony Minessale]

freeswitch uses unique ip/port pairs so freeswitch sees that was 2 different
addresses the
0.0.0.0 was considered another ip.

0.0.0.0:1234
1.2.3.4:1234

We will maybe add code to make 0.0.0.0 fatal input as rtp-ip to avoid this
issue.
