I thought I read someplace that if you block your outgoing CID, then Verizon to Verizon calls are treated as off network calls and your minutes are used.
This was the case until about a year ago. It was that the person with the blocked number would use VZW to VZW minutes however the person that got the private call would use regular minutes.
VZW has since fixed. All calls between VZW customers are free (assuming you have that included in rate plan) even if a number is blocked.
