[Freeswitch-users] Outbound Gateway hang up at 30 seconds with no answer

[Ken Rice]

NAT or similar related issue. let me guess called party is sending a bye to you 30 seconds after the they send the 200 OK?

they are most likely not getting the ACK for the 200 OK. look at your trance and see where the ACK is getting sent to
