It looks like your question is a bit brief. Could you please clarify what you mean by "how to call private"? Are you asking about:
- How to call a private phone number?
- How to call a private method or function in programming?
- How to make a private call on your phone (e.g., hide your caller ID)?
- Something else related to "private call"?
If you specify which context you mean, I can provide a detailed and helpful answer!
