Just curious about RTT/TTY calls.

Could it have been initiated by a caller, with an android?

As I recall, Android phones have a similar feature. So, yes.

How long is the transcript stored?

iPhones store the last 100 calls in Recents. So, how long, time-wise, would depend on how many calls you make and receive on your phone.

For any Legal Eagles: Can it be used as evidence in a court of law?

That is a question you should ask a lawyer. Never take legal or medical advise from random strangers on the internet.

Make or receive RTT/TTY phone calls

• Open the Phone app.
• Select your contact and tap their phone number.
• Select RTT/TTY or RTT/TTY Relay.
• Wait for the call to connect, then select RTT/TTY.
• Enter your message. If you turn on Send Immediately in Settings, your recipient sees your message as you type.
