Session Initiation Protocol (SIP) is a widely used standard for establishing, managing, and terminating communication sessions, typically involving audio and sometimes video, and is central to VoIP and unified communications systems. It enables integration between devices such as speakers, intercoms, and cameras, allowing seamless communication across networks. SIP systems range from simple peer-to-peer setups to advanced architectures using servers or PBXs that provide routing, scalability, and additional call handling features. It also supports SIP trunks that connect to traditional telephony networks, making SIP a flexible and scalable solution for modern communication and security integrations.
