A comm needs 2 RTP streams, most of (good) softphones forbid an odd port number in order to keep things clear: they give you an even port, and the next one is the RTP "return path" of the same comm.
Actually, a comm is 2 RTP streams but they use the same port on both ends (endpoint A port X <------> endpoint B port Y>. The next port (often the odd one) is "used" by RTCP, so let's say it's unused as RTCP is not really widely used, but another RTP stream should never use this port, as it could lead to some strange things....
