The way businesses operate is changing and a well equipped VoIP system will mean that staff can work on the move following a ‘one number approach’ with true mobile integration.

What is VoIP?

VoIP is short for Voice over Internet Protocol. Voice over Internet Protocol provides the technology to use an Internet connection for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions of the PSTN (the traditional copper network). For an optimum VoIP service, a quality broadband connection is required.

Why switch to a Hosted VoIP system?

For most companies there is a strong possibility that you are working much differently compared to how your business was working back in 2009 when the on-premise phone system was installed.


Your business may now offer remote/home working to your employees, but has your office phone system kept pace with those changes in working practices? Chances are it hasn’t, and you have created a work around.


The Gamma Horizon Hosted business VoIP Phone system delivers modern working practices and provides a high-quality experience for staff whether they are in the office or home-based. For those businesses with a desire to manage the phone system themselves, an easy to use Gamma Horizon Portal is also available to manage moves and changes when required, putting you in full control from an administration perspective.


The Broadsoft Call Controller platform is a leading platform in the world of cloud-based telephony and it’s also at the heart of our business VoIP phone systems services too. This provides assurance that you are working with the very best technology in the Global Voice solutions marketplace.
