IP Trunking (also known as SIP Trunking) lets you run all of your data and voice traffic – local, long-distance and private branch-to-branch communications – on a single IP backbone that seamlessly connects your company to the public switched telephone network (PSTN). Opening up an important new avenue in convergence, IP Trunking leverages your existing IP-based connectivity by eliminating the need for separate voice and data networks. It also offers significant potential savings when compared with multiple PRI (Primary Rate Interface) connections to the PSTN.

Now all of your business communication systems, no matter how complex and geographically dispersed, can run over a single, secure network. And by reducing your infrastructure costs and management time while supporting legacy PBX implementations, IP Trunking can increase the return on your existing technology investment.

Gain the flexibility to meet changing needs.
IP Trunking gives your network scalable capacity, allowing you to increase or decrease the number of PSTN connections and associated bandwidth without installing additional PBX hardware – all using a single software application. You only pay for the bandwidth you need, whether you are:

• supporting special sales promotions and campaigns
