What is a SIP software engineer?

A SIP Software Engineer is a professional who specializes in developing, implementing, and maintaining software solutions that use the Session Initiation Protocol (SIP). SIP is a signaling protocol widely used for initiating, maintaining, and terminating real-time communication sessions such as voice, video calls, and messaging over IP networks. SIP Software Engineers typically work on VoIP (Voice over IP) systems, telecom applications, and related networking technologies. Their responsibilities may include designing SIP-based applications, troubleshooting signaling issues, and ensuring interoperability between different communication systems.
