This appears to be someone picking up PIA from domain registration and trying to do who knows what with it. The area code is 208 (Idaho) and is the same as my own.
The caller seemed to have trouble starting the conversation, there were a few "hello?"s back and forth before she got to asking me if I was in charge of a particular domain name (I said yes, after I asked her to repeat) and then she immediately asked if I had a fax #. Given my domain is no where close to expiring, giving out additional information seemed inappropriate so I said "no" and hung up.
