Hi Nanang, Thanks again. But the first issue still remains, how will my application going to get the RTCP messages (RTCP APP or TBCP) from the remote servers? Let me explain my problem again : Media Proxy sitting in between two servers, both servers can send RTCP APP msgs to Media Proxy and then send RTP bursts. 1) MediaProxy will recv. RTCP APP msgs from Stream1. 2) I will take out the RTCP msgs, make some changes in it and pass it to Stream2. 3) Then when the Handshaking is done for RTCP msgs. 4) I will start getting the RTP stream data from stream1 and put it to stream2 (doing decoding on stream1 and encoding on stream2). So for RTP data, just calling pjmedia_port_get_frame(stream1) and pjmedia_port_put_frame(stream2) will get decoded data from stream1 and put the encoded data to stream2 and vice versa. Now for RTCP,? i just want to get the RTCP packet, parsing/modification i plan to do in my application. I am not very clear how transport adapter (pjmedia_tp_adapter_create()) can help me in this, because it assigns its own callbacks for RTP and RTCP. Whereas i have already created two streams which have assigned there own callbacks? Is it possible to get the RTCP packet which is returned by on_rx_rtcp() callback function assigned by both streams stream1 and stream2?

The media transport adapter will do the pre/post RTCP packets processing, i.e: before sending an RTCP packet it inserts the customized part into the packet, on receiving it parses the customized part.
