How do I Recognize a TTY Call?
It is important to recognize whether an incoming call is a voice or TTY connection when one telephone number services both types of calls. When incoming TTY calls are answered by voice, the listener hears either a series of beeps, a high pitched series of tones, or a long silent pause. DONíT PANIC and DONíT HANG UP on the caller. Most TTY users understand that it will take some time to hook up the TTY to the telephone. If the telephone line is dedicated to the TTY, you can assume it is a TTY call and proceed to connect the telephone receiver to the TTY couplers.
