Hosted Voice/VOIP and SIP

Business phone systems

We provide a spectrum of services to meet business communications on site or remotely; from fixed line rental to cloud based voice and data networks that integrate communications between devices.

Cloud-based / Hosted telephone systems

A modern phone system 

The future of business phones

With better quality data connections available, VOIP and cloud-based technology is becoming increasingly more popular for businesses who are looking for a reliable, cost-effective and flexible telephone solution.

How does it work?

Cloud-based phone systems are hosted in the cloud rather than in your office using Voice over Internet Protocol (VoIP) to communicate. This simply means all phone calls are placed over the internet through a data connection rather than traditional infrastructure, perfect for remote working and online collaboration.

An improved way of working

Boost productivity and improve customer service

With cloud-based communications, your staff and customers benefit from a seamless calling experience. Exceptionally clear audio quality, minimised call dropping and unified communications not only improves staff productivity but also improves general customer satisfaction.

Business Continuity 

One of the main benefits of cloud-based phones is the ability to make and receive a call from anywhere with an internet connection. Whether you’re working from home or on the road, cloud-based applications can be used on multiple devices, meaning your staff won’t miss a call. 

In control and flexible

Your organisation’s entire communications can be managed easily through a simple to use interface. Cloud-based solutions are highly scalable – changes can be made to multiple sites, countries and individual users through one portal. 

Integrated Communications

A seamless experience

Work collaboratively with integrated messaging, video meetings, call routing and unified communications.

Working alongside your existing tools

Create a streamlined experience by integrating hundreds of apps such as Office 365, Salesforce and G Suite. 

Management reporting

In-depth call management reporting and dashboard integration is available to help organisations get a real-time understanding of their call traffic.
