[OpenSIPS-Users] Opensips as outbound proxy to Freeswitch

[Bogdan-Andrei Iancu]

Hi David,

The "relay forbidden" case happens when neither the FROM URI, nor the 
request URI contain a SIP domain served/local to OpenSIPS. In your case 
I see that the INVITE has in FROM and RURI the 192.168.0.46 SIP domain. 
Is your OpenSIPS actually listening on this IP ?
