SIP (Session Initiation Protocol) is a communication protocol used to initiate, manage, and terminate real-time voice, video, and messaging sessions over the internet. It is the core technology behind modern VoIP (Voice over IP) calling systems.

  1. Call Initiation
    When a user places a call, SIP sends a request (INVITE) to start the session.

  2. Call Routing
    The SIP server locates the recipient and checks availability.

  3. Session Setup
    Once accepted, SIP establishes the call parameters (codecs, IP addresses, ports).

  4. Media Communication
    Actual voice or video flows through RTP (Real-Time Transport Protocol), while SIP manages signaling.

  5. Call Termination
    When the call ends, SIP sends a termination message (BYE) to close the session cleanly.

Key Components of SIP

  • SIP Client – Phone, softphone, or AI calling system

  • SIP Server – Handles call setup and routing

  • SIP Trunk – Connects VoIP systems to the PSTN (public phone network)

  • Codecs – Convert voice into digital packets

  • Supports voice, video, conferencing, and messaging

  • Highly scalable for businesses and call centers
