Abstract
An apparatus and method communicate TTY calls by detecting a TTY call, determining that a digital display on a first telecommunication terminal is to be used to display TTY information of the call from a second telecommunication terminal and that audio information will be transmitted to the second telecommunication terminal, converting the TTY information from the second telecommunication terminal to digital display information, transmitting the digital display information to the first telecommunication terminal, and muting an incoming call audio path from the second telecommunication terminal to the first telecommunication terminal.
