This happened to me at ROA on a clear day. We were informed after configuring the aircraft.

1. I answered the phone becuase the possibility existed she was going to inform us of an emergency, even though she did not select the emergency call button. No guarantee a scared flight attended watching a fire growing at the back of the aircraft isn't going to revert to the way she calls us 99 times out of 100 to inform us.

2. Mountainous terrain. Continuing the landing ensures the least risk to the pax who aren't in the lavs.
