But at first Sight the Stack is not handling SIP/415 responses correctly since it actually lacks the mandatory "Accept" header with the media types PJSIP/PJMEDIA supports. Without that information the peer will obviously never know which of both medias was the troublemaker in its offer ;o) My proposal was to add Accept: audio/* in the 415 Response, if the offer contains *ONLY* streams PJSIP doesn't support for the moment.
