What is SIP Trunking?

Traditional phone service has customers paying per-line for a physical phone line that originates from a central office. These types of phone systems are expensive and can cost a lot of investment upfront. Not to mention scaling is an added expense. With SIP Trunking, phone calls are routed over the internet.

SIP Trunks modernizes your existing phone system. Alternatively, it can provide the cost-savings you need to purchase a new phone system. Start cutting your operational costs today by contacting Centra IP Networks.

Replace Your TDM-Based Services

TDM, or time-division multiplexing, is so old school! You need a solution that allows you to scale up or down easily and increase capacity whenever you want. SIP Trunks are more cost-effective for your business and save your team countless headaches by reducing complexity.

Isn’t it time you experienced true flexibility? With our Advanced SIP Trunking, you can redirect your calls instantly in the event of any disaster. Which means your business keeps running smoothly when you need it to.
