Hi, What I would like to do is to park an incoming call and then play a background music while it is parked. Upon occurrence of certain event, I would like to unpark the caller again and bridge it to someone else. I tried to use the following: switch_status_t status = switch_ivr_play_file(session, NULL, set_bg_prompt_data, NULL); switch_ivr_park_session ( session); It does not work. The call goes to hangup and it does not "wait" there. Does anyone know what is wrong and how to accomplish my goal? thanks, jb
