RTP will either place then in a buffer to be played out or, of they are too late, will disregard them. It must be this way, because UDP does not know how late they are. The timestamp is part of the RTP protocol. 25th March 2006 at 06:28 #30812 STANISLAUSGuest thanks Author Posts Viewing 3 posts - 1 through 3 (of 3 total) The forum ‘Voice over IP’ is closed to new topics and replies.
