You can use anonymous call to block your identify and phone number from appearing to the recipient.
You can also select an Unknown or Blocked caller ID in the TeleConsole's general or phone settings (see web, Android, or iOS versions) or use Telebroad's Private Caller ID dial code to achieve the same result.
