Star Codes aren't required to begin with a star. I defined a star code "1" followed by 10 digits. This star code will set Block CallerID then call the 10 digit number.
Define a Star Code:
1(xxxxxxxxxx), Block Caller ID, set($Bci1,1), call($Code)
Dial 11 digits to block CallerID. Dial 10 Digits to pass CallerID.
