caller ID displays: INTL. NUMBER and a local number. Seems as tho this INTL. NUMBER uses other people's local area codes too.

First call was a woman (didn't recognize the accent) asking for a person who works here by name. After the call he said that it was a free subscription to a professional magazine.
Another call a couple of hours later from the same number was a recordering for credit something with instructions to press "2" to be removed from their list.

Called my phone company to find out what was up, but they were no help. Said that the caller ID might be the name of the company.
