Hi My setup is : gateway <=> freeswitch<=> cisco CUCM In freeswitch I bridge a call from gateway to cucm using sofia/gateway/gw1/dest dialstring, where gw1 is a trunk to CUCM in external profile. when fs receives 180 from cucm it is not forwarding it to gateway so caller hears nothing. I found out this by "sofia global siptrace on". is it normal? should I set some variable so that freeswitch forwards "Ringing" to gateway? It seems I should execute ring_ready but I want to know the correct way of doing this. thanks
