4.10 Support for Callers with Impaired Hearing

TTY is a method of sending and receiving text messages within the speech path of telephone calls. The text is entered and displayed through a TTY device, such as a text phone, connected in parallel with the user's normal telephone. Due to its widespread usage and support it has become the standard used by devices for the users with impaired hearing or vision.

Voicemail Pro 1.4 and higher supports the addition of TTY prompts for leaving messages in and collecting messages from Intuity mode mailboxes. Callers with a TTY device can see the TTY prompts and leave TTY format messages. The mailbox user, also with a TTY device, can collect and display those messages by following the prompts that are displayed on the TTY device.

The TTY device and associated analog telephone (linked either by a pass-through port on the TTY device or a telephone splitter) are connected to an analog extension port (POT) on the IP Office system. During calls the TTY can be used to display and send TTY messages. The analog telephone can be used to send dialing digits and provide a speech path during calls.
