Everyone is talking about cloud or hosted services especially with telephony, but there are still some environments when an on premise solution is more advantageous.
On-premise telephony (where the phone system hardware and software are hosted at your own site rather than in the cloud) offers several clear benefits, especially for certain types of organisations.

A Device and App for Everyone
On premise solutions offer a range of IP handsets and softphones suited for businesses of all sizes and industries.
You can take advantage of high quality hardware and/or a softphone on mobile devices and laptops/desktops and optimise your time in or out of the office.
We’ve listed some of our more popular devices to give you an idea of what’s available.

Benefits and Considerations for On Premise Telephony
- Internal calling continues to work even if internet connection goes down – ideal for education, hospitality, large campuses;
- Predictable long term costs – lower recurring subscription fees;
- Ideal for organisations with one or few permanent sites rather than highly mobile workforce
- Good for mixed estates with CAT 5 and legacy cabling
- Advanced features still being developed for on premise
