Got a call this morning from this number. The man asked for my friend, but stumbled on her name. When I asked to take a message he refused. I asked if I could tell her who called and he said "Who am I speaking to?" I asked him the same back. He gave his name as "Chris" and said he'd call back later. Seems sketchy to me!

Apparently the number is unlisted--it doesn't show up on a reverse look-up.
