A SIP (Session Initiation Protocol) trunk is a service provided by a telecom carrier that enables businesses to connect their on-premises phone system to the public switched telephone network (PSTN) using an internet connection. SIP trunks allow businesses to make and receive phone calls using their existing phone system, while taking advantage of the cost savings and flexibility of internet-based communication.


SIP trunks are an alternative to traditional phone lines, such as T1 or PRI lines, which use dedicated copper wires to connect a business's phone system to the PSTN. SIP trunks use a virtual connection over the internet, which can be more cost-effective and easier to manage than traditional phone lines.


To use a SIP trunk, businesses need to have a compatible phone system and an internet connection with sufficient bandwidth to handle voice traffic. They also need to purchase or lease a SIP trunk from a telecom carrier, which will provide them with a unique SIP address and any necessary configuration details.


SIP trunks are often used by businesses to reduce their telecom expenses and improve the efficiency of their communication systems. They can also be used to enable features such as call forwarding, voicemail, and caller ID.


An example of a SIP trunk would be a telecom service that allows a small business to connect its on-premises PBX (private branch exchange) phone system to the public switched telephone network (PSTN) using an internet connection. The small business could then use its PBX system to make and receive phone calls as usual, while taking advantage of the cost savings and flexibility of internet-based communication. The SIP trunk provider would provide the small business with a unique SIP address and any necessary configuration details, and the business would pay a fee for the use of the SIP trunk.
