actually, your passing these to originate, … but your not setting anything on the session doing the originate, ringback should be there, not in params iirc.  Possibly instant_ringback as well.  We should probably have better docs on which leg vars effect.

I tried with with and without setting, when I copy/pasted below was the without. It didn’t seem to matter.

switch_event_add_header_string(ovars, SWITCH_STACK_BOTTOM,  "ringback", "%(2000, 4000, 440.0, 480.0)");  

Should I set it differently? Maybe that’s my issue.

do you set the ringback var too?

Guys,

I’m trying something that is seemingly so simple but isn’t working for me. I want to ignore early media and provide instant ringback.

My module is written in C. I’m 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. It’s getting the vars ok because I can tell it’s 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.

Here’s 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);
