A TTY Caller ID unit attaches to a TTY device or standard phone and displays the name and telephone number of callers before the call is answered. It stores telephone numbers, dates and times of calls even if callers hang up or don't leave messages. New equipment includes a flash button that lets TTY users switch back and forth between two calls. Call Waiting Caller ID requires a special display unit or telephone that works with both services. TTY users should ask service reps about Distinctive Ring service, which can be used to let you know whether an incoming call is for the number assigned to the TTY or the number assigned to the telephone.
Connection is free, too.
