The messaging system at Aisling Discoveries permits callers to select prompts in voice or TTY format. If a caller wants to leave a TTY- format message, the message will be recorded by the system and then stored in the same mailbox that holds the called party’s voice mail. Therefore, it is not necessary to provide separate call-in numbers for voice and TTY users.
Support for TTY users does not end with call-answer capabilities. TTY users have access to nearly all of the same mailbox functions that are provided to voice users via the telephone user interface, such as the ability to generate, receive, and forward messages, do directory look-ups, and return.
