Who called from 4085243000

registering your number with the crtc DOES NOT WORK.  we did it several years ago and the number of telemarketing calls INCREASED.  nothing but a waste of time

Been getting phone calls from that number! How do I stop it?

Got a phone call from 408-524-3000 March 9, 2015.  Apparently some security system.  Female caller had an accent.  I have my phone number listed on the "do not call" list.  Well so much for that program.  These people annoy me.
