What are SIP Trunks?

SIP stands for Session Initiation Protocol, and the word “trunk” in VOIP (voice over ip) world refers to a link that can connect multiple parties to one another at the same time. When used together, SIP trunking refers to the way the new, digital version of voice calling technology establishes a connection with the other end.

Before SIP became a popular and reliable method of transmitting voice signals, the Public Switched Telephone Network (PSTN) carried all telephone calls. The PSTN is the network that has those copper phone lines we traditionally associate with the “telephone.” The PSTN is a circuit-switched network, which requires a physical connection between two points to complete a call. Analog phone lines and PRI’s were common terminology used before VOIP.

SIP trunks are basically virtual phone lines that enable users to make and receive phone calls over the internet to anyone in the world with a phone number.
