Analogue, ISDN2e, ISDN30e

Traditionally Analogue and ISDN lines were provided to customers to enable calls to be made. The technology has since moved on and the standard provision now is to provide VoIP to enable all types of call to be made.

Analogue lines come either as a single line or a group of lines, respectively allowing one incoming or outgoing call at a time, and multiple incoming and outgoing calls on one telephone number. A group of analogue lines can be used for regular desk phones or attached to a telephone system offering a range of additional features.

ISDN lines are digital and offer greater call clarity and also additional features such as allowing each person in the office to have their own direct-dial number.

We can still install new Analogue and ISDN lines until 2023 where there is currently no alternative. We can also still take them over and manage them for you. By the end of 2025 all customers will need to have been migrated to VoIP as BT are planning to cease all Analogue and ISDN lines by then.
