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 existing contact information associated wit an incoming call to provide context to a user for accepting incoming calls and during conversations and may apply various display settings. For TTY users, the additional context simplifies the ability to conduct critical reasoning, especially those with cognitive impairments. In particular, a picture from the user's address book is provided to assist in identifying the caller. The other display settings may include modified font styles, colors, multi-line display etc. to differentiate between incoming and outgoing messages.
