Magna5 recognizes that not all businesses are alike, and neither are their voice requirements.  Session Initiation Protocol (SIP) Trunk service is a solution for companies looking for a fast, scalable, and easy to implement solution that works with their existing telephone system (PBX). Introduce direct-inward-dial (DID) phone numbers without the expense and constraints of a traditional primary rate interface (PRI) circuit. Enjoy bundled usage to avoid high fees incurred by many business long distance phone service plans. And along with your DID, you’ll have a rich feature set, including SIP Trunk failover.

Magna5’s SIP Trunk solution leverages your existing in-house technology to support your organization’s phone service voice calls, and control your monthly communication expenses. Rely on our carrier-grade, IP network to expand your business communications to include any IP enabled device, including: SIP phones, Softphones, tablets or laptops.

What is SIP Trunking?

With a traditional phone system, customers pay on a per-line basis for physical phone lines. It is very expensive and resource-heavy to deploy, manage, and stay up-date with traditional phone systems. SIP trunking eliminates these issues because phone calls are routed over the Internet.

SIP Trunking can work in tandem with your existing phone system, bringing new life to your system in place. Keep your existing phone system and numbers to eliminate the hassle of new setup and installation. SIP trunking can provide savings by cutting operational costs and capital expenses.
