Should I leave my work hours on voicemail?

I am having to use my own personal phone, with a Google number to communicate with clients.

They call after hours, on the weekends etc and it's annoying. I work Monday-friday,, 9 to 5, yet I have someone who called yesterday night and this morning.

Do you think it'd sound odd to leave hours on voicemail? I want them to stop calling me on the damn weekends and when I'm home
