I'm home office. We just moved. I don't have to get a lot of customers to update my contact info, my phone number stays the same.
Sometimes I go into the corporate office. My work number rings my desk phone there too.
My work number rings my home office phone, my corporate office desk phone, and my cell phone. My cell phone is not a great only phone. Since the demise of flip-phones, people tend to have a hard time hearing me on "candybar" style smartphones that do not get long enough to reach both my ear and my voice.
In my case, it's convenient.
I've never used transcripting or anything else. To me, it's only a phone number. I have seen a few voicemail transcripts from GV. Tremendously terrible. Not worth seeing again, so that feature is disabled.
