Reliable services from a stable company

Companies depend on Callsure Business Telephone & Fax Numbers for business-critical communications, and count on us to deliver a reliable and continuous service. We have devoted a great deal of time and effort to developing a set of extremely stable services and a reliable network. And unlike many ideas-led technology companies, our combination of real-world focus and fiscal prudence ensures we'll be here far into the future. Our balance sheet is in good shape!

Choose us as your telecoms supplier and enjoy the benefits of proven technologies from an established, financially stable company: We minimise your risk and exposure to IT problems by being 'obsessed by quality' at every turn.

Well-established upgradable technologies

The network behind our services has been running for over a decade, founded on a profitable business that's been trading since 1991 - with no intention of being acquired or being dependent on third parties.

Flexible and reliable, the network integrates a growing range of technologies including PSTN telephony and Voice-over-IP (VoIP). We approach all 'bleeding-edge' technologies with healthy scepticism, and only launch new services when they are fully-tested.

Customers never get 'locked' into dead-end technologies. They can add new services at any time, and change price plans at will. So when their business changes, the call-handling services they use can change in step.

Full transparency and detailed account information

Our web controls give access to the most detailed call information in the market, allowing customers to monitor calls and costs at all times. Incoming calls (even those that were never answered) are itemised against full billing information and callerID.

We can even help you retrieve 'lost' faxes and voicemail. All messages are kept on our servers for 90 days, and can be accessed and resent using your number's web-based control panel.
