Duet^SM SIP Trunking service from MegaPath delivers full-featured business-class phone service and lightning fast 1.5 Mbps Internet T1 service for less using your existing IP-PBX system. This service combines both voice and Internet, so you pay for only one circuit, saving your business money. Since you use the IP technology you've already invested in, there are no upfront costs, and no new equipment or phones to buy so you can start saving today.

Unlike consumer-grade VoIP, MegaPath’s Duet service never rides the public Internet so your phone calls are always crystal clear and the reliability, security, and overall performance are second to none. In addition, we make it easy to switch your service with no start-up costs or downtime.

Business Features that Make Sense

With MegaPath Duet SIP Trunking you can get as many phone numbers (DIDs) as you need, so all your employees can have their own phone number regardless of how many lines you purchase. Duet SIP Trunking also includes optional dedicated port(s) for fax machines, alarm systems, and other devices. With unlimited local and low per-minute rates for long-distance calling, caller ID and call waiting, you can enhance the performance of your existing digital PBX with features that make sense to a small-to-midsize business.

* See Duet Term & Conditions for details.

***E911 service will not be available if there is a power failure, a disruption in the T1 line, or a malfunction of the broadband router. MegaPath strongly recommends that you maintain an alternative method of calling emergency services at all times.

How It Works

Duet^SM SIP Trunking is a business-grade voice and data service with up to 24 phone lines and up to 1.5 Mbps of T1 Internet access.

When you sign up for our Duet SIP Trunking service, MegaPath installs a private T1 circuit at your location, with specialized voice/data routing equipment on either end. Your traffic is delivered over MegaPath's robust, private all-optical MPLS network, allowing us to prioritize voice traffic over other data traffic. This ensures crystal clear voice service and the reliability you expect from a business-class phone service.

Duet SIP Trunking is compatible with your existing phone system so you don't have to buy new equipment. You can even keep your existing number and add additional DIDs (Dedicated Inward Dial) to provide unique phone numbers for each of your employees. There's no downtime because we don't port your numbers over or connect your phones until your Duet SIP service is in place.
