Least Cost Routing - Other Schemes

If you use BT's 'Light User Scheme', and similar lower-cost schemes such as 'In Contact' and 'In Contact-Plus', you will not be able to use these schemes and CPS. To take CPS, you will first have to cancel these schemes.

On the other hand, if you already use CPS but want to use one of these schemes instead, you will have to cancel the CPS service. Also, if you want to change other services you receive (for example by adding new lines); you will need to find out how the CPS service will be affected.

What happens if I have a burglar or personal alarm that uses the telephone?
If you are considering using CPS on a line intended for a burglar or other type of alarm service, it is strongly recommended that you check with T1 Telecom’s first. (You should note that CPS will make no difference to the existing 999 emergency services number.)
