I have been bidding reserve, by choice, for the last seven winters. I live in base and am about twenty minutes from the airport. I choose to let the call go to voicemail 90% of the time. And 95% of the time they call it's for an assignment for the next day.

Never once has a scheduler asked me if the reason I didn't answer the phone was deliberate or because I was otherwise tied up. Prompt is prompt, it doesn't mean immediate.
