Requests for Comments (RFCs)

Request for Comments (RFC) documents are fundamental to establishing Internet standards, including those for the Session Initiation Protocol (SIP). These documents provide formal specifications and operational guidelines that are vital to ensuring interoperability and standardization on the Internet.

Adherence to relevant RFCs is not just about compliance, it's about ensuring compatibility and future-proofing solutions. SIP, as a core protocol for initiating, maintaining, and terminating real-time sessions across Internet Protocol (IP) networks, is governed by a suite of RFCs. These documents define everything from the basic protocol mechanics to advanced features and best practices.
