ISDN Lines are an old style digital line that enable multiple numbers across multiple channels to be provided to an in-house telephone exchange. We do provide these but they are in the process of being superseded by SIP Trunks.

These costs for these are as follows:

Installation - £200.00 + VAT

Transfer of existing line - £0.00

Monthly Rental - £26.00 + VAT

Calls charged for on an as and when basis

There is a minimum period of 12 months

If multiple numbers are required then this can be provided but incur additional installation and rental costs.
