I never take solicitations over the phone no matter who they say they are. Matter of fact don't disclose any information no matter how innocuous it might seem over the phone to anyone unless you are absolutely sure you know who it is you are talking to and they need that information. For example
you called your insurance company...
People will use the phone to fish for information and telling them something that might seem harmless can have some bad consequences.
