I did not answer because I don't know anyone from this number. Calls are coming in to my landline. This time the call came from Hayden AZ. But before, the call came from this same number, but from a different Az city -- Casa Grande, Cottenwood, Safford, Benson, Tucson. I'm so sick of all these callers. I think I'll just turn my ringer off and check for "real" calls every so often.
