Guys, I¹m trying something that is seemingly so simple but isn¹t working for me. I want to ignore early media and provide instant ringback. My module is written in C. I¹m setting ignore_early_media and instant_ringback to true in a switch_event header and passing it in via the ovars param to switch_ivr_originate. It¹s getting the vars ok because I can tell it¹s ignoring early media, but there is no ring back to the caller. Are there other flags I need in conjunction with these two to hear ringback? I must be missing something. Here¹s a code snippet. switch_event_t* ovars = NULL; switch_event_create(&ovars, SWITCH_EVENT_REQUEST_PARAMS); switch_event_add_header_string(ovars, SWITCH_STACK_BOTTOM, "ignore_early_media", "true"); switch_event_add_header_string(ovars, SWITCH_STACK_BOTTOM, "instant_ringback", "true"); switch_status_t rc = switch_ivr_originate(session, &sipSession, &cause, data, timelimit, NULL, caller_name, caller_num, NULL, ovars, SOF_NONE); Thanks in advance.
