SIP Trunking

Harness the power of flexible connections

Vertical SIP Trunks

Vertical SIP (Session Initiation Protocol) Trunks replace your traditional, fixed public switch telephone network lines, enabling your phone system to make and receive calls via the Internet for a significant savings as well as scaling to meet your needs, automatically. With SIP trunking, you gain efficiencies from transmitting voice over the same bandwidth, and perhaps most importantly, you open the door to the latest solutions such as mobility, instant messaging and video. Vertical SIP Trunking can help you extend the life and utility of your telephone switch by facilitating the connection of remote offices to your PBX, creating virtual call centers, setting up disaster recovery and unleashing the latest collaborative capabilities.

SIP Trunking

A Better Connection for Your Business Communications

SIP Trunking replaces the physical connections to your communications system with less expensive and more flexible SIP connections. SIP Trunking eliminates the need for traditional analog, T1 or PRI lines and moves your business into the advanced world of IP communications.

Savings & Scalability Today Enhanced Services Tomorrow


SIP Trunking is a future-proof solution that expands in lockstep with your business. Unlike traditional PRI connections, our service lets you buy exactly the number of call paths you need, so you can right-size your costs.

Our SIP Trunking service has been tested for interoperability with all major SIP-enabled PBX brands. Not on our list or need to keep a traditional connection to your PBX? Gateways can connect your PBX to our service.

SIP Trunking preserves your PBX investment while easing a future upgrade to a hosted PBX service. With SIP Trunking, you can take advantage of cloud services such as call recording immediately.

With traditional PRIs, adding capacity takes time because physical connections must be installed. Our SIP Trunking service can be increased to any capacity that the IP connection will support within hours or less if needed.

In the event of a emergency or when all lines are busy, SIP Trunking allows you to immediately and easily reroute traffic to another location or phone number, so you never miss a call.

With SIP Trunking, you get predictable monthly costs and unlimited local and long distance calling. Plus, we offer competitive international rates when needed.

SIP Trunking

Less Cost, More Flexibility

Often the tradeoff for lower-cost services is reduced functionality. Not with our SIP Trunking service – you get the quality of a traditional connection plus a unique set of features. That’s because SIP (Session
Initiation Protocol) supports voice calls, conference calls, multimedia and more. Plus, SIP transmits call-related
info, such as caller ID, enabling enhanced functionality.
