Rtt/tty

My rtt/tty button is off but when I call someone it keeps opening and interrupting my call. How do I remove it or disable it?

iPhone 8 Plus, iOS 13

Turn off Answer All Calls as RTT/TTY.
Turn off Hardware TTY.

RTT is a more advanced protocol that transmits audio as you type text. iPhoneprovides built-in Software RTT and TTY from the Phone app—it requires no additional devices. If you turn on Software RTT/TTY, iPhone defaults to the RTT protocol whenever it's supported by the carrier.

Set up and use RTT and TTY on iPhone - Apple Support
