- Identify the noisy task’s likely duration and the actual quiet window needed.
- Choose an order both people can use and ask before extending the noise into the protected period. A short call need not reserve silence for the whole day.

An invented example to adapt, not a real exchange or a script you have to follow.
Before you leave it here
Confirm the actual call window rather than assuming quiet is needed all day.
