Numbers Overview

Callagenix provide a comprehensive range of phone numbers covering over 100 countries and many thousands of cities around the world.

You select a number which meets your requirements; whether it’s a Toll Free (Freephone) 0800 number, local, national or international number, or even a revenue generating number. Then you decide how the number will best work for you.

Some telephone numbers can simply be diverted to your landline absolutely free of charge.  Alternatively by combining selected numbers with one or more Callagenix Advanced services, you can benefit from very sophisticated call routing; normally associated with buying expensive PBX or switchboard hardware.

*Note - if you need to keep your existing number, but still want access to Callagenix services, you can do that too: Click here to find out more.
