Voicemail should be banned

When I had a work mobile phone in Australia I had my voicemail saying I was on leave and to call the office.

The boss wasn’t happy, but the customers actually called the service desk because of it.

Is that not normal? Most businesses do that in Canada. Auto email response, change voicemail to contact X or the receptionist.
No, almost everyone I know would have “leave a message and I will call you back.”
