Numbering of RTCP packets must adhere to RFC 3550. Please see section about odd and even port numbering. Most PABX manufacturers adhere to this ruling. Basically, all RTP packets must carry an even port number and RTCP packets must carry an odd number. For example: If your RTP port number is 2000 then your RTCP associated port number would be 2001. RTCP port number is always one value higher than that of the RTP port. TEAMS does however not adhere to RFC3550 and as a result you will see odd and even numbered ports.
