Carrier Pre-Selection (CPS) is a mechanism that allows end-users to select, in advance, alternative Communications Providers to carry their calls without having to dial a prefix or install any special equipment at their premises. The end-user subscribes to the services of one or more CPS operators (CPSOs) and chooses the type of calls (e.g. all national calls) to be carried by them. The end-user may have a direct retail relationship with the CPSO, or may purchase the service via a CPS Reseller. The end-user is billed for these calls by the CPSO or CPS Reseller.

A simple solution

CPS is fully automated. So there's no need for new equipment and the caller doesn't 
  need to dial a special prefix for their call to be routed via your chosen network. It's available to anyone with a BT line on a wide range of line types, including PSTN, ISDN, Featureline and Featureline Embark.

Built-in flexibility

Because CPS is applied on a per-line basis, it can be configured to suit your needs. You can choose which types of calls are subject to CPS. And you can apply CPS to a line in a number of configurations to suit your calling profile. Lastly, CPS is cost-effective and very reliable.
