I received a call from 636.534.0250 that said "I have a call coming through."  I waited a few seconds then heard another couple of "please hold" and "we'll be right with you" messages - then a series of tones - then more, different tones - then a hangup.  I tried to call the # back directly and with and without 1+area code (even though we're in the 636 area code, some 636 #s are LD) but each time received a telco message that the number had been disconnected. Weird.
