SIP Trunking Solutions

Converge Voice and Data over a Single IP Network and Maximize Your IP-PBX Investment

About our SIP Services


Our SIP trunking solutions branded as nexMatrix Hosted Solutions SIP Service or SIP Trunking Solutions, a division of nexMatrix Telecom, Inc., unifies voice, data and internet services over an IP connection, leveraging your existing IP-PBX. It’s a perfect solution for a single location business with 10 or more phone lines. nexMatrix has been providing SIP service for more than 12 years now!

Based on the Session Initiation Protocol, a SIP trunk provides the connection between your network and the public switched telephone network (PTSN). With this SIP trunk connection, you can make phone calls from your IP-PBX device without additional physical wiring, thereby reducing the recurring costs of separate voice and data circuits and the costs associated with the purchase, support and maintenance of media gateways.

nexMatrix SIP trunking can be delivered over your existing broadband internet connection in most cases, or on dedicated direct circuits that deliver an unparalleled SLA with always-on, prioritized voice traffic channels.

Integrated access combines your voice and data onto a common access circuit, enabling you to achieve greater economies of scale and simplify the management and maintenance of your communications infrastructure.
