VOIP Phone Systems

As technology has improved over the last decade, we find that more and more of our customers are taking advantage of the capabilities that business voice over IP has to offer (VoIP).

A VoIP call is a voice call placed over the internet rather than a traditional fixed copper line or mobile network. VoIP is quickly becoming the most popular way to communicate with businesses because communicating over the internet offers increased quality and much more flexibility over a traditional Integrated Services Digital Network (ISDN) solution. Business Voice over IP can help to reduce the cost of calling between sites and can enable your staff to work productively from home whilst gaining all the benefits of being sat in the office. This solution is also perfect for growing business as it can be easy to scale up. At NT Voice & Data, we’ve pioneered very cost-effective ways to allow gradual adoption of VoIP that minimises investment whilst ensuring you gain all the benefits of this technology.
