Droid X - Incoming private number blocking also per call outgoing number privacy.

[Jocosa]

I have a Droid X and I am looking for ways to either block or send to voice mail numbers that come in as blocked/private. As well as a way to hide my number, on a per call basis, when I make outgoing calls.

I have Googled and read various "How to" sites but most the replies are old and don't work, or the apps suggested don't exist anymore. They also offer various combinations of *(somenumberhere) options to try but those have not worked either.

Is there a current, working app that can do both? Or if need be 2 apps I can use?

Thanks in advance for any and all suggestions and help!
