Session Initiation Protocol (SIP) is the technology that enables businesses to make calls over an IP connection. It’s a way of providing telephone lines using data, instead of a fixed line.

As more and more businesses are moving over to SIP, Fibrenex is on-hand to provide total flexibility, allowing you to carry your number with you and even market your business locally around the country. The benefits of moving over to SIP include the decrease in costs, greater flexibility than a standard fixed line and enabling you to maximise your network assets.
