I use a variation of your system with two phones. One is like yours and I always hawe it with me, turned on. The second is for everyone else - delivery people, banks etc. I have it muted except if I expect a call. Every couple of days I check it only to find that there were no important calls. Once a year someone leaves a message and I call them back. This system works great, I don't remember when was the last time I had to deal with scammers and other people wasting my time.
