[Freeswitch-users] Bridge event socket channels with early media

I have developed a event socket application to handle my business logic with greater channel control. When internal user make outbound call it calls socket application and connect with the server, then server make outbound call using xml_rpc api with socket application parameters like ["&socket({0}:{1} async full)"] and that channel also connect with the server.I want to bridge channels before answer in-order to A-leg to listen telco messages such as "user not in service area". What is the proper mechanism for achive this. Regards, Sukitha
