H.263 is the initial release developed by the ITU-T Video Coding Experts Group and originally designed as a low bitrate compression to be used in H.324 based systems (PSTN - POTS) videoconferencing. But was then also used in H.323 (IP), H.320 (ISDN) and SIP (IP) videoconferencing. A=rtpmap:34 H263/90000 indicates that PT 34 is assigned to H.263.
