So which rudeness is worse? At least the landline cost is fixed each
month, and not per minute of call made.

Is it also rude that I am out an awful lot and thus unlikely to answer my
landline except at a pre arranged time?

No, that's just life; and your mileage varying. Someone is "in" at our
household most of the time.
