Note: BT use two different types of telephone exchange to provide the Featureline service, System X and System Y. You need to know this when using the following troubleshooter.
If you don’t know which exchange type you are on, please lift the handset and dial *#001#
If the message you receive begins with the word "Sorry", you’re on a System Y exchange.
