How do I make calls using a telecommunications device for the deaf (TDD) from my AT&T CallVantage phone?
The TDD can be connected to the Telephone Adapter just like any other telephone (either by plugging it directly into the Telephone Adapter or by connecting it through the in-house phone wiring). However, before connecting the TDD to the Telephone Adapter, it is essential that the ‘Fax and Modem Support’ option be turned on for the line to be used with the TDD. Once connected, customers can use their TDD to make calls by dialing ‘711’ to reach the AT&T Telecommunications Relay Service (TRS) center.
