My question is simply this. If two males who are living in the same house with the same last name and are family members (in this instance it is an adult male son over age 21 with bio. parents) and one has a wife all three uses the same land line as their primary phone # for work, doctor, etc etc etc.... If the husband dies (and the phone is in the dead man's name) is the wife required to tell everyone who asks for Mr. "Smith" to say he's deceased and immediately hang up without another word, or ask which Mr. "Smith" they want, or why they are calling before saying that her husband is dead, or handing the phone over to the other Mr "Smith"
