theres another thread on the
theres another thread on the forum where some providers let you do it in this manner
exten => s,1,SipAddHeader(P-Asserted-Identity: <sip:${CALLERID(num)}>)
exten => s,n,SET(CALLERID(name)=hidden)
exten => s,n,SetCallerPres(prohib_passed_screen)
not without custom programming otherwise you will break your billing cdr. It depend on if your provider accepts a P-Asserted-Identity sip header info for real callerid. You technically arent allowed to actually remove call data off the call. If one of your subscribers commits a felony using block callerid and you are unable to recover the true call detail information the FCC will shut you down. What a lot of LEC's decided to do is to mark a call private but then put the original callerid in P-Asserted-Identify.
