An internet telephony service provider would provide SIP trunking to enterprises that want to make full use of their installed IP-PBXs and communicate internally and externally over IP. Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk allows a company to replace these traditional fixed PSTN lines with PSTN connectivity via a SIP trunking service provider on the internet.
