But after having tons of headaches because of the searching on any example which demonstrates using of the RTP APIs we did not found any thing.so we need any RTP example to demonstrates the steps and the scenario which must be followed to implement the part of our project who concerning with the transmission using the RTP .

Any help in this regard is highly appreciated.
