After investigating further, I suspect these calls are coming from the University at Buffalo fund raising phone bank.

In the past week I received two calls from different numbers, but beginning with 716-645-xxxx. I last attended UB over 40 years ago. I no longer answer unknown numbers, but in the past have received such calls from UB. I support the university, but never respond by phone to charitable requests.
