Received a 1037 second (17 minute) voicemail from this number on Nov 5 @ 4am.  It was all FAX tones.  I can almost bet the call came through on my toll free number to boot!  A***oles.  Who's FAX machine tries for more than a minute if the handshake fails?

I would chalk this up to telemarketers sending their crap via FAX as NO ONE would try to FAX me on the number they called.
