Summary:A communications network is configured to operate using real time protocol (RTP) within internet protocol (IP). RTP payloads comprise: a fixed length carried frame bit map defining whether data for each of a plurality N+1 of possible timeslots is present in the payload, and a variable length body containing the data defined as present in the carried user frame bit map. This allows cheaper transmission of voice frames over IP because N+1 (e.g. 32) voice frames can be multiplexed inside a single RTP packet. This permits an increase in the ratio of user data per packet to packet size so, in turn, increasing bandwidth efficiency.
