I was out of town for the weekend and when I came home to check my messages and caller i.d. I had 9! blank messages and 14 phone calls. As late as 12:26 AM! eastern time!
Multiple calls daily over 10 days - no message and no live voice - I checked the # on-line last night and it came back as belonging to Paetec Communications in Los Angeles on W 4th St about 7 blocks SE of highway 110 at exit 234 according to the google map - that appeared to be a local transit terminal.
