i keep my phone in my purse which for some reason isn’t ever within reach. My solution has been to pretend I’m Dick Tracy (for those of you who remember him) and aim my voice at my Apple Watch. Works great and the folks on the other end report that the transmitted audio is great. I should admit I’m surprised when my watch rings and vibrates and indeed it takes a few seconds to realize the phone is nowhere in sight and I can answer the call with the watch. Works well for Apple people and there’s probably a similar Android solution.
