Carrier Pre-Selection (CPS) enables Call Flow to carry all of your outbound calls without the need for you to enter an access code, use any form of dialler or even have your telephone system (PBX) re-programmed. You keep your existing telephone numbers and continue to make telephone calls as usual.

The network access technology used by CPS allows traffic originating from your location to be re-routed automatically as the access code is inserted by BT at the local telephone exchange. Activating CPS is a very straightforward and automated process. After authorising Call Flow to switch your calls to our network, the changeover is managed by BT and takes around 10 working days to complete.

With CPS, you can choose to keep your telephone line rental with your existing provider or for more convenience and a single supplier, why not move it to Call Flow at the same time?
