You can work without calls for sure and choose to avoid them if that works for you, please don't be in the position of managing team for the teams sake. This is a blatant misunderstanding of how the teams are built and run. Being in a role and doing a good job in your role are completely two different things.

If one wants to be a good manager then you do not have the luxury of being in good or bad mood, you are required to context switch between more than one person with entirely different motivation and problems.
