Carrier Preselect (CPS) Belgacom / Mobistar

 What

Carrier Preselect (CPS)

 Problem

I had a problem that I couldn't fax out anymore over a Belgacom PSTN line (Mobistar customer)

 Solution

The client has a Belgacom PSTN line, but the subscription was with Mobistar. After I made some calls, I realized that when your subscription is not with the same provider for the cable you have to set a Carrier Preselect. A CPS is used for concurrent providers on the same cable, when you dial the CPS first before the number, your call will be routed through the chosen provider.

In Belgium the most CPS's are:

Prefix Provider
1510 Toledo Telecom
1515 Telenet
1522 Orange Business Belgium
1525 Scarlet Business
1551 Belgacom
1555 BT
1566 Verizon Business
1588 Scarlet Business
1595 Mobistar
1599 Belgacom
1602 T2 Belgium
1611 T2 Belgium
1616 Colt Telecom
1636 TalkTalk Direct Limited
1661 Telenet
1665 Verizon Business
1666 Verizon Business
