And one of the easy things, we can do, is take a look at an experiment, in this case, I captured packets using Wireshark for a 2150.12 seconds long Voice over IP call.  And during this call, there a 107,505 RTP packets in each direction and another 429 RTCP packets in one direction.  So, the RTP packets (of those packets) containing the voice and the RTCP packets were are carrying information about the RTP traffic. And these were transferred in only one direction.
