Other Signaling Systems

• MSP:

  The Media Sessions Protocol unifies many of the best ideas associated with the current crop of Voice-over-IP (VoIP) and media protocols used in the Internet. MSP uses peer-to-peer location discovery and signaling and a centralized user identifcation authority similar to Skype. MSP uses encryption of all message traffic similar to Skype using key exchanges similar to ZRTP. MSP uses a NAT-friendly design based on a single transport address similar to IAX2. MSP uses a simplified text-based signaling protocol similar to SIP. MSP uses standard RTP for media transport.
