摘要
A method to prevent TTY/TDD (teletypewriter/telecommunications device for the deal) probing and unwanted TTY/TDD tone generation on voice gateways comprises detecting a PSTN textphone in a call path, if any; and providing visual clues to an end user, thereby avoiding generation of unwanted text by the end user. The visual clues may be in the form of a dialog box on a computer, warning messages on a phone, and/or the like.
