Hi, Supposed A make a call to B, but B does not pick that call. In this case who detects the missed call, A or B ? Here are 2 cases I think 1. A itself detect that after a timeout T (30s for ex_, A doesnot receive 200 OK 2. B itself after timeout T (30s for ex), it sends DOES_NOT_PICKUP response to A How is missed call implemented in pjsip ? -- Khoa Pham HCMC University of Science Faculty of Information Technology -------------- next part -------------- An HTML attachment was scrubbed...
