Y U No

I made a contact in my phone named "telemarketer" I add them to this contact and set the default ringtone for that contact to silent. That way if the same one tries calling more than once I never hear the phone ring.

An app called "mr number" does a very good job with that.

I need to get that then! Thanks for suggesting it!

A word of caution, pay close attention to your settings :)

Good call! I will make a note of it! :)
