I would like to avoid giving out my personal line to coworkers. I’m looking for a voip service that

• Receives calls/text on desktop and phone (android)
• Can be configured to turn off outside of work hours automatically.
• Inexpensive. It’s not going to be used much, but is still necessary. I don’t want to pay much.

I believe the business version of Google voice does all these things, but as far as I know the cheapest plan would still cost me >100 a year.
