Block Caller ID for specific manual outbound calls

Voice & Telephony
1

I would like to know if we can send any extensions in RequestMakeCall to block caller ID for specific calls only.

Options that I have tried already and works are:

  1. Create a specific trunk for such calls and put privacy there. (I want to avoid this)
  2. Use CPNDigits to mask the original number.

Any ideas?

TIA
