SIP Trunking

SIP trunking is a Voice over Internet Protocol (VoIP) and streaming media service.

It is based on the Session Initiation Protocol (SIP)[1] by which Zest4 deliver telephone services and unified communications to customers equipped with SIP-based private branch exchange (IP-PBX).

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.

SIP trunks can offer significant cost-savings for enterprises, eliminating the need for local PSTN gateways, costly ISDN BRIs (Basic Rate Interfaces) or PRIs (Primary Rate Interfaces).
