I am trying to send RFC 2833 tones using the pjsua_call_dial_dtmf() method in an iPhone app that I am working on. The method executes without producing any errors, but analysis of the call traffic shows that the RCTP event is not being sent. Are there any configurations that I need to set to enable RFC 2833 tones when sending a call? Right now I am also considering trying the other 2 methods of sending RFC 2833 tones such as pjmedia_session_dial_dtmf() or pjmedia_stream_dial_dtmf(), but I am unsure how to determine parameters such as, pjmedia_session * session unsigned index pjmedia_stream * stream here is a snippet of my current code that I am running, pj_str_t* digits = (pj_str_t*)[digit UTF8String]; status = pjsua_call_dial_dtmf((pjsua_call_id) current_call, digits); if (status == PJMEDIA_RTP_EREMNORFC2833) { error("Error sending tone", status); } Any feedback would be greatly appreciated.
