What is SIP trunking?

SIP Trunking is a technology that allows businesses to send voice and other communications over the Internet using the Session Initiation Protocol (SIP).

“Trunking” refers to the aggregation of multiple voice or data connections into a single link for more efficient communication.

It connects an organization’s on-site PBX (Private Branch Exchange) to the Internet, enabling calls to be made and received over the web, bypassing traditional telephone lines and reducing costs while providing scalability and access to advanced features.
