Session Initiation Protocol

Session Initiation Protocol (SIP) is used for realtime communications. It can be used for VoIP phone calls, and is also used for messaging and video conferencing. Functions can be activated and terminated as needed during a session.

SIP can be used to connect to more than one location a participant may be working from.

SIP includes metadata for each participant. The fields will indicate each person’s location, whether or not the communication is secure, and give information on their communication capabilities.

SIP checks to ensure that the participants are using compatible devices. It will determine the correct codec to use, widening the range of less sophisticated devices that can connect to the session. (A codec is used to decrypt a data stream.)

SIP works with both VoIP and regular, old-fashioned landlines.
