Block Caller ID

[sickness]

Hi;
I am thinking about a project that can block the caller ID in the
telephone. I was searching for more information about the project but
unfortunately I couldn't find. Please, provide me with more information
and is that project possible or not. ???
I appreciate your quick reply in advance.
Thanks

What exactly you want:

1) your phone number not to send to the person you call

or

2) to block the incoming number (for displaying at the CallerID) that calls you?

Hi;
I want to do the first choice((my phone number not to send to the person you call ))

Then the only choise is to enable PRIVATE number from your local telephone line provider. This is a feature that most of the telephone providers offer for free or for a small charge depending the company.

I don't think there is another way to do that
