Making the move to Demon Voice couldn't be simpler.

If you wish to purchase Demon Voice for more than 12 analogue lines or multiple office locations please contact our product specialists on the above number.

The order process should take around 10-15 working days to complete.  During this time you will receive a welcome letter from Demon informing you of your ‘service live’ date – which simply means the date all your calls will start to go over our network. You will still receive a BT bill for your line rental each month and any other BT chargeable features.

During this time if you have any questions regarding your order, please contact our customer support centre on 0845 272 2666.

Please read the checker before ordering the service:

•  I have a BT line.
•  I do not have Centrex-based lines (Featureline or Featurenet).
•  I live in England, Wales or Scotland (unfortunately this service is not available in Northern Ireland).
•  I do not use meter pulses.
•  I do not have ‘Internet for schools’ package.
