You should understand that this is only the tip of the iceberg. If you just needed an introduction, it is OK to stop here. But for bigger things you must go through RFC 1889 and that is not enough. You have to work yourself to be a master in applications employing RTP.
RFC 1889 has been superceeded by RFC 3550. Thanks to John York for pointing it out.
At this point, I will strongly recommend that if you are serious about the subject please go through some of the books listed in the books section.
If you have any suggestion, correction, query just mail to
