Note: TTY audio mode activation may not be possible while a
telephone call is already in progress.
NOTE:
If a normal headset is connected while TTY support is
enabled, the audio quality may be decreased.
If a Bluetooth headset is connected while TTY support is
enabled, the audio quality will not change because TTY
audio mode has not been activated.
However, if you make a phone call using a Bluetooth
headset while TTY mode is enabled AND a plug has been
inserted into the headphone jack, TTY audio mode will be
activated and voice quality will decrease.

Remove the plug from the headphone jack or
Uncheck the Enable TTY support checkbox in the Start
menu > Phone > Tools > Options > TTY tab.
Disabling TTY Support
To disable TTY support:
