This sounds like a variation of hell for specialist retail. You want the sale and that call from the customer making an enquiry is your chance to make sure you are going to be ready for them. You want to have them arrive to ask for you by name to continue the sale. Small businesses, e.g. the hair salon, should have a student or someone on the desk who can take the calls so the working staff don't have to. There are ways to be succinct on the phone and to wind things up without wasting customer time. I don't believe Google have a clue about customer service and I don't believe any ultra clever AI robot solution can help. Nobody phones up their local supermarket to 'see if they are open' or if the 'stock tinned peas'. In specialist retail you want to take the call and convert it into a sale. I don't believe this product really helps with that. I also am aware that 98.3% of customers have Googled a business before they step inside the store (in the realm of specialist retail or services). So you really want to markup your web homepage with the required JSON-LD for the opening hours, address details and other basics that would be a meaningless interruption. In that way people don't even have to call. If people are calling up about these things, e.g. holiday opening hours, it is not a phone solution that is needed, it is basic information on the website. We have created these amazing ways for people to contact us, with it people create more remarkable ways of hiding. Not answering the phone, not answering emails is the norm, businesses should not be hiding this way out of courtesy.
