Hosted Telephone Systems

Powerful Features. Nothing to Maintain.

What is Hosted PBX & VoIP?

Hosted PBX (Private Branch Exchange) is the modern version of the traditional telephone closet. The new hosted, or “cloud,” model puts the brains of your phone closet into professionally maintained data centers, helping businesses like yours to transform their communications and improve productivity—without the need to purchase expensive, complex, depreciating phone system software and hardware.

We manage and monitor your system 24x7, allowing you to focus on work. VoIP refers to phone services that are accessible through a high quality broadband connection. VoIP is typically more cost effective and scalable than traditional alternatives. With both Hosted PBX and VoIP, you and your team can work from the office, home, or on the road, or through your smartphone, all while utilizing your company’s communications solution to help maintain and uplift your image and brand.
