[Freeswitch-users] No ringing is heard if carrier sends 180 Ringing - works fine when 183 Ringing (with SDP and RTP)

Hello, Here is the call scenario: - a-leg is bridged/connected to b-leg - They both are put on hold. a-leg listens to music, b-leg hears a prompt - A call is originated to c-leg: originate and park - If originate is successful. c-leg and b-leg are bridged together: uuid_bridge - b-leg does not hear ring back tone of c-leg of carrier send 180 Ringing, but would hear the Ring back tone if it's played from far end through RTP (183 Ringing) I have tried various things but haven't been able to make it work. b-leg hears dead air until c-leg actually answers. I can't not play any thing to b-leg either. Is there a way to make this work? Any suggestions? Thanks, Ali Pey
