SIP Trunking Overview

Your telephone service is your vital connection to your customers, remote and mobile employees, partners, and suppliers. Phone technology has changed more slowly than other communications technology, but now is a great time to look at SIP Trunking technology, which delivers more capabilities at a significantly lower cost than traditional phone services.

Many businesses use traditional TDM lines for voice communications needs, but this requires two different network infrastructures and the costs associated with two networks. SIP trunking allows voice and data communications to utilize the same network, resulting in lower costs and greater flexibility and ability to respond to growth and changing demands.
