No idea who this is...the automated message on my machine seemed cut-off.  It started by stating, "If you'd like to place this call on hold, press 2.  If the person is not available, press 3".  I didn't listen any further because it was really odd.  The Caller ID displayed "888-664-9461" as the name, but I can't find any info on that either.

Same number and Caller ID called again last night.  This time I listened to the whole message on my answering machine.  The auto-voice seems to start while my outgoing message is playing and picks up with "If you'd like to place this call on hold, press 2.  If the person is not available, press 3," then there's a few seconds of silence and the call disconnects.
