The Text Relay service is accessed via the PSTN and enables communication for textphone users i.e. between 2 parties in either text to text mode or text to voice mode. A relay assistant will provide voice to text conversion on text to voice or voice to text calls, while text-to-text calls will not use a relay assistant.

Callers will prefix the required number with an Indirect Access code (18000/18001/18002) depending on their requirement.

Available to all BT Customers.

Users do not need to be registered for the service, all chargeable calls will appear on the caller's telephone bill i.e billed to the originating line where the call was made from. A relay assistant will provide voice to text conversion, while text-to-text calls will not use a relay assistant. Callers will be charged at the appropriate PSTN rate for the A to B call. There will be no additional charges incurred against the Text Relay conveyancing or the relay assistant. i.e. for charging details prior to the affects of the appropriate Text Rebate see the Price List in Section 2, against the relevant call types:

A rebate is applied to the text element of all valid calls originated via 18001 or 18002 when either or both ends are in text mode. This rebate is only applied to parts of the call which are in excess of the minimum charge i.e. no rebate is applied to the part of the call which is less than the minimum call charge for that call.

e.g. a call with 50% text (on the element call greater than the minimum charge) to a destination with 60% rebate will attract 30% rebate (to the charges above the minimum charge).
