I run a 24 hours attendant on duty coin laundry.

My work number is listed on google business.

My staff makes about 20 calls a month.

We have no presence online or social media.

I have spectrum business internet at the laundry.

I want to get rid of Spectrum Business phone charges.

I still want the staff to be able to make calls to customers and use the physical phone.

And I still want to be able to call the laundry and speak to the staff in an event of an emergency.

How can I get rid of the spectrum business phone charges without losing the business number?

TL:DR, I have been paying to spectrum for the business phone service I almost never use.
