What is SIP Trunk and How Does It Work?<\/strong><\/h2>\n\n\n\n

A SIP trunk refers to two things. SIP (session initiation protocol), which is the protocol used to start and end a call, and a trunk, which is a term adopted from traditional telecommunications. A trunk cable is a cable with a lot of copper pairs that are designed to facilitate many concurrent calls. <\/p>\n\n\n\n

In the same way voltage travels through an analog telephone pair, RTP (Real-Time Transport Protocol), travels across a session in a SIP trunk. RTP, is the audio portion of a call, and the quality of that audio has a lot to do with the network it\u2019s traversing. A reliable, low latency connection to the internet is critical to the success of a SIP trunk.<\/p>\n\n\n\n
