Screen shot of a RTP frame from SampleCaptures file: rtp_ In SIP and other protocols a RTP session is described by SDP (Session Description Protocol), which is not really a protocol itself but rather a formalised way to describe a media session. Instead, the ports are allocated dynamically and then signalled using a different protocol such as SIP or H245. RTP does not have a well known UDP port (although the IETF recommend ports 6970 to 6999). UDP: Typically, RTP uses UDP as its transport protocol.The current RTP RFC is 3550, dated July 2003. The protocol supports the use of RTP-level translators and mixers. RTP and RTCP are designed to be independent of the underlying transport and network layers. ![]() The data transport is augmented by a control protocol (RTCP) to allow monitoring of the data delivery in a manner scalable to large multicast networks, and to provide minimal control and identification functionality. RTP does not address resource reservation and does not guarantee quality-of-service for real-time services. RTP provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video or simulation data, over multicast or unicast network services.
