This is by far one of the most simplest yet effective ways to stop wrong number calls from invading your cell phone [1]. Thanks to Baby toolkit [2], if you follow these simple steps, you won't have to deal with Eddy looking for Freddy, or in my case Tifinity looking for Gigi (true story!).

• Create a contact on your phone called wrong number.
• Whenever a repeat wrong number offender calls, add them to the wrong number contact.
• Change the wrong number contact ringer settings to silent.
• Whenever one of your wrong number regulars calls, your phone shouldn't make a sound!

And hopefully when they keep getting your voicemail, they'll realize that Gigi has new number!
