Received call from 949-565-3746, answered but no sound, so called back to see if client (was listed as Irvine, CA number).  A robocall answering machine said "Thank you for calling, the survey is over, thank you"

5/1/17 @ 10:53 AM to 949 area:  Caller ID shows it as "Irvine CA."  I made the mistake of answering it, so now they know MY # is a working number; no doubt I'll get more of these in the days/weeks to come.  Anyway, there was only SILENCE from their end, nothing said; after about 10 seconds they disconnected the call.
