Android :: Regarding Audio And Video Send / Receive On Android

Android provides a use-friendly API for playing and handling media (audio/video).However, I have the following requirements which i wish to realize with this framework: My requirement is to have knowledge of the ports that the android media framework opens and uses for sending/receiving media streams. I use this information for signaling on the Session Description Protocol (SDP) that i add as a payload to SIP.Is it possible for me to get this information in the form of a RTP session from the framework ? (ports and address combination).*Use Case for this requirement:*If I initiate a multimedia call towards a peer, I will need to open my audio and video ports and start streaming media once the signaling is complete and successful. For successful streaming, the remote end needs to have knowledge of the ports I have opened for media as the streams are bi-directional and I will also need to receive media from the remote end.(sendrecv in SDP) . This is for the outgoing call.
