First, get the 'groupsock' object associated with the "RTPSource":
         Groupsock* gs = yourRTPSource->RTPgs();

Then, get its socket number:
         int socketNumber = gs->socketNum();

Then, get the source port:
         Port resultPort;
         if (!getSourcePort(env, socketNumber, resultPort) {
                 env << "Failed to get source port: "
                     << env.getResultMsg() << "\n";
         } else {
                 portNumBits sourcePortNum = resultPort.num():
                 // Note that this is in network order; call ntohs() 
to get host order
         }
