This number and another (same except for 1 at the end instead of 7) called at 8:57 and 8:58 this a.m. A message was left demanding a return call from my first wife (we divorced in 1990), so no doubt a collection agency with poor research capabilities. I use AT&T so I gather this is a number that comes in from a variety of callers who block their Caller ID, however I was not given an opportunity to accept/reject the call.
I received a call that was blocked with Privacy Manager so I hung up and immediately got another call from the number above. Caller ID said the name was "Leave a Message." I hung up and as soon as I hung it the phone rang again from the same number. I thought maybe it was a telemarketer or collection agency.
