Three rings and then nothing. Calling at "dinner hours" doesn't make any difference since some of us are still AT WORK. I consider being bombarded by ANY unwanted call a telemarketer, regardless of their intent.
This number is calling my cell phone! Looks like it's a survey/research company. I've unplugged my home phone because of these &!?@#%^.€! calls. And now they're using my cell?! How do I stop them?!
