What is Cloud Telephony?

Hosted Telephony, also known as “Cloud telephony” or “VoIP” moves the functions of your on-site phone system (PBX) and all the expensive equipment it requires, into the cloud. Instead of connecting telephones to an on-premise phone system NX phones are connected through your broadband (Wi-Fi or Data for mobile devices) and connect to multiple secure data centres across the UK. This means you always get crystal clear voice quality. NX delivers all the standard features of your current phone system as well as the advanced features you’d expect to pay much more for, without any of the expense and maintenance of an on-premises PBX. This is all delivered seamlessly to desk phones, computers, and mobile devices.

You can cut down your telephone line rental costs, all you need is a line for your broadband either from us or your existing provider. With 2000 free minutes to 01, 02, 03 numbers and 2000 free minutes to UK mobile networks per user each month*, your telephone bill will be looking very different with NX.
