What is SIP trunking and how does it work? SIP trunking allows businesses to make and receive local or long-distance phone calls and other digital communications over the internet, instead of traditional phone lines.
SIP stands for Session Initiation Protocol, which is a signalling protocol used for establishing, maintaining, and terminating real-time sessions that involve video, voice, messaging, and other communications applications and services.
SIP trunking works by establishing a virtual connection between the business’s private branch exchange (PBX) and the service provider’s PSTN network over the web. https://oal.lu/EEDAq
