Abstract
A method and system are provided that examine incoming and outgoing TTY transmissions to determine an identifier for distinguishing between correspondents in a TTY call. The system may utilize contact information associated with an incoming or outgoing call to provide visual distinctions, and/or flow control, to the text from each party as it is displayed on a TTY device.
