1.7 Versioning and Capability Negotiation

This document covers versioning issues in the following areas:

  • Supported Transports: This protocol only supports [MS-RTP] as its transport, as discussed in section 2.1 and [MS-ICE2] in TCP mode only.

  • Protocol Versions: This protocol, as a payload format of RTP, does not provide versioning information within the scope of the protocol itself. However, as a part of the RTP payload, any versioning information about the RTP level applies.

    The current version is 0x00080004. The current RDP version number can be obtained as described in [MS-RDPBCGR] section 1.3.1.1.

  • Capability Negotiation: Capability negotiation is done by non-RTP means, usually through a higher level application layer protocol such as Session Initiation Protocol (SIP) and Session Description Protocol (SDP).
