Q. How do I change from dialing numbers to dialing letters (touch tone mode)?
A. Using a remote control:
On your remote control, hold down the pound (#) button (a/A also appears on this button). This toggles between numbers (123) and letters/touch tone mode (abc or ABC). Depress the pound (#) button and then hold it down again to toggle back to number (123) mode.
Note: Letter (abc/ABC) mode is also known as touch tone mode.
In letter (abc/ABC) mode:
To type @, press 1 twice on your remote control while in letter (abc/ABC) mode.
To type a full stop/period (the . symbol), press * once while you are in letter (abc/ABC) mode.
Using an endpoint's keypad:
To toggle between numbers (123) and letters (abc/ABC), hold down pound (#) on your keypad.
To type @, press 1 twice on your keypad while in letter (abc/ABC) mode.
The button you use to select a full stop/period (the . symbol) on your endpoint is selected differently depending on your model. See the endpoint documentation for more information.
