What is SIP Trunking?
Traditionally business calls are routed to the Public Switched Telephone Network (PSTN) over individual lines or 23 channel PRIs from your local telephone company. SIP Trunking effectively performs the same function by delivering voice calls over a dedicated IP connection from the LightEdge network that can be used to simultaneously deliver Internet, WAN and Hosted Application traffic.

SIP Trunk Voice-over-IP is a flexible and reliable voice solution that allows your company to save money and prepare for the future. As your business grows beyond the capability of your existing PBX, a hybrid voice model allows you to add hosted voice seats onto your existing platform until your PBX is fully depreciated. At that time, you can make the decision on converting all users to Hosted PBX.

Business Benefits of SIP Trunking

• Realize economies of scale through a single source for both voice and Internet service - Dynamic bandwidth management allows your voice and data to be delivered over the same high-speed connection. Quality of Service (QoS) measures ensure the highest call clarity available regardless of Internet traffic. Because multiple services are provided by a single vendor, management is easier through a single point of contact and a single monthly invoice.
  
  
• Leverage your current investment while preparing for the future - SIP Trunks allow your business to continue to use the existing PBX and scale beyond its capabilities by migrating additional users to a Hosted PBX seat. Regardless of the voice delivery method, all employees are interconnected using the same voice network. When you are ready to phase out your legacy phone system, the remaining employees can be moved to Hosted PBX as well.
  
  
• Reduced Calling Costs - SIP Trunking gives your business access to reduced per minute fees for toll-free, long distance and international calling; plus free calling between on-net locations and virtual workers.
  
  
• Layer Voice-over-IP features to increase functionality - With a SIP Trunk you can add Voice-over-IP features that aren’t currently available through your PBX. This “Personal Mobility Pack” allows a user to access the latest enhanced mobility features through the secure, hosted LightEdge Advanced Voice Solutions platform.
