Keep your existing 01603 number
Already have a 01603 number? You can move it to Voxora through number porting and keep it exactly as it is. Porting is normally free, your number does not change, and your calls simply start ringing on the new system once the transfer completes.

Because the number runs over the internet, you keep that local identity even if you move premises or work remotely.
