Messaging supports a teletypewriter (TTY), a data terminal that people who are hearing impaired or speech impaired can use to transmit and receive text through a telephone system.
Messaging supports TTY with the Audix TUI only.
Messaging does not provide automatic TTY support in Messaging mailboxes. Administrators must enable TTY support. Administrators can configure mailboxes so that callers can select the TTY language or voice prompting from the same mailbox. The administrator must install the US English TTY language pack to support TTY.
The TTY prompts make most Messaging features available to users of TTY devices. Messaging users can send, receive, and respond to TTY messages with a TTY device. Users press the same telephone keys to send, receive, and respond to TTY messages and voice messages.
Users whose mailboxes are set up for TTY can:
Use the TTY language for most Messaging menus, prompts, and messages.
Use Messaging to answer incoming telephone calls with a TTY greeting.
Callers can use the Messaging TTY or voice prompts when they record messages. Messaging also supports the use of TTY and voice during the same call. For example, a user can receive a prompt in TTY language and then record a voice message. Hearing impaired people who speak clearly can receive messages with a TTY device and send a voice message during the same call.
