If you are in a committed relationship should your mate be allowed to answer your phone?
I wouldn't think it would be a problem, as long as your mate is only trying to answer for your convenience. Maybe I'm old enough to remember when the phone hung on the wall. The personalization of everything has gotten a bit much.
I don't have much to hide, so it does not bother me that much.
The answer is “No” unless given permission. And only to the extent the grantor grants it.
