Cloud-based IP Telephony

Our Cloud-based managed IP telephony service is a hosted VoIP service designed specifically for businesses. Unlike the traditional approach of installing a physical PBX system at each office, all telephony switching equipment is hosted at our secure, high availability data centre facilities. The HD quality Cloud telephony service is then delivered over our IP network direct to your offices, with IP phones connected to your office LAN.


The Cloud-based design of our hosted IP telephony service is particularly suited to dynamic and growing organisations as it can be quickly changed to fit your requirements, and staff at home or remote offices get exactly the same functionality as their head office colleagues. Multi-sited organisations looking to move to hosted IP Telephony will benefit from significant cost-saving, as well as increased operational efficiency, resilience and business continuity - as a distributed carrier-grade IP telephony (VoIP) system, if a component fails a backup takes over without impact.

Cost savings

The traditional voice landscape involves expensive in-house infrastructure: The ubiquitous 'tin box' telephone system bolted onto the wall which - following sometimes considerable upfront expense - comes with a nasty catch in the hidden expenditure of upgrade, maintenance and running costs.

Our managed Cloud telephony service model is different: There are no upgrade or maintenance charges. It's a straightforward monthly licence fee on a per user basis. A simple pay-as-you-go model with a compelling punch line - a new IP telephone system for about the same price as the maintenance charges on your old one. There's no ISDN line rental charges and no maintenance or upgrade charges, just a significantly reduced predictable monthly charge.
