Try this
- Choose one fallback before the next call: an audio attempt, a short text, or stopping for the day.
- Set a limit on retries. A single message can confirm that the technical interruption was the reason the call ended.
A worked example
“The picture froze again. I’ll try audio once; if it still drops, let’s stop and pick another time.”
An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Check whether the fallback actually reduced effort. Do not interpret a device problem as a deliberate exit without asking what happened.
