  • Detection of TTY's using programmable filters
    Publication number: 20060056598
    Abstract: A method and system are disclosed for detecting a call made to the system, answering the call, and optionally, plays an announcement. The caller responds by, pressing a DTMF key or keys, sending TTY tones, speaking a response or doing nothing. A user who presses a TTY key or keys, or a TTY device that sends an auto-ID string generates TTY tones and the system detects TTY tones of at least about 30 milliseconds and greater. The system connects the call to another person, platform or portion of the service logic specifically designed for TTY calls.
