1.What is SIP

SIP (Session Initiation Protocol) is a signaling communication protocol, which is widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) network. The protocol defines the message that are sent between peers, which govern establishment, termination and other essential elements of a call. The SIP version we currently support is SIP 2.0.
