Just received call from this #. If I don't hear a response within 1 second I hang up.  Hardly ever get callbacks as this is a computer generated calling service.  Hopes this helps

Survey bot with female voice asking about cell phones. Wasn't smart enough to realize it was leaving a voicemail.

just called me but didn't respond to my "Hello" so I hung up.  I have the TeleZapper so maybe they had already been cut-off by the time I said Hello

Customer looking for a vehicle called from this number

Just had a call from recorded lady's voice, based in QUE, doing a short survey.  I hung up after a few seconds.  This was on my unlisted cell phone too.

Those f***ing calls!
