SIP trunking (Session Initiation Protocol) is a VoIP technology through which you can receive and make calls over IP (VoIP calls) using a broadband connection. SIP trunking is based on network data connectivity which stamp out the need for a fixed telephone line.
ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) telephone connections can be replaced by SIP trunking. ISDN transmit data and voice over a digital line through circuit-switched telephone network system. The digital line may use copper line to replace the outdated landline technology with digital. While, PSTN is operated by local, regional and national telecommunication companies. Landline telephone calls are made through connected circuit-switching public telephone networks and can be owned by phone service providers.
SIP trunking technology enables you to connect your PBX (Private Branch Exchange) to PSTN through any form of internet connection which can be broadband, mobile data or an ethernet connection. With the help of SIP trunk service providers businesses, large corporations and contact centers can be connected through unlimited number of channels. In comparison to ISDN and PSTN lines, SIP trunking provides much more flexibility in usage of geographic numbers, as long as you have internet connection you can make long distance, local and international calls. Sip trunk is very quick to install and provision.
