SIP trunking is a digital telecommunications method that delivers voice, video, and streaming data over an existing internet connection rather than legacy copper telephone lines. It directly bridges an on-premises PBX or cloud phone system with the public switched telephone network. This setup allows businesses to replace traditional telephone lines, centralize multi-location calling, and scale concurrent call channels dynamically without having to purchase physical wiring or proprietary hardware.
