Telephone system integrated text based communication processes to enhance access for TDD and/or TTY devices

摘要

A process of handling a TTY call from a calling party to a called party receives a TTY call to the called party; checks a database of at least one party capable of receiving the TTY call from the called party to determine whether the called party is able to receive the TTy call; and if the called party is in the database, then prompts the calling party to leave a message; receives the message; stores the message; and notifies the called party that the calling party has left the message. In addition, the process may also check a second database of at least one party capable of receiving the TTY call from the called party and if the called party is in the database, then prompt the calling party to leave a second message; receive the second message; store the second message; and notify the called party that the calling party has left the second message. The database contains parties having access to a text server and wherein the second database contains parties having access to a voice mail system, the voice mail system capable of handling the TTY call.
