I've searched through pjsip source (sip_transaction, sip_dialog, sip_inv) but still cannot find one that handles "not receiving INVITE ACK". I think callee must disconnect call when not receiving INVITE ACK Also, I have some other questions 1. Why is media transport start in state CONNECTING? why not in state CONFIRMED ? 2. Why does pjsip not create new transaction for ACK packet (according to RFC 3261) ?? 3. Why does ACK packet have the same Cseq as previous INVITE and INVITE 200 ? -- Khoa Pham HCMC University of Science www.fantageek.com -------------- next part -------------- An HTML attachment was scrubbed...
