Text telephone (TTY) mode is used for text communication over a telephone line. A TTY device must be connected to the computer to interpret the modified audio; otherwise you might experience poor audio quality during the call. Using TTY mode in a conference call may also cause audio quality issues.

TTY mode is turned off by default, to turn on the feature:

  1. Connect a TTY device to your computer.

  2. Click Turn on TTY mode, under Phone accessibility.

  3. Sign out of Lync, and then sign back in.
