SIP Trunking

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

It is based on the Session Initiation Protocol (SIP) 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).

Zest4 offer a full range of traditional telephone line solutions both to support connectivity and data solutions and for scenarios where hosted solutions are not applicable due to connectivity coverage and performance challenges.

Whatever your customer’s communication requirement, Zest4 can provide the solution.
