Sending outbound calls with no caller-ID....somtimes

no callerid or callerid blocking? there IS a difference. Is this a PRI? SIP trunk?

This is a SIP trunk....didn't know there was a difference.

yes, you legally aren't allowed to place calls without an ANI, or an invald ANI, or an ANI that doesnt belong to you.

try a custom script that does this

exten => s,1,SipAddHeader(P-Asserted-Identity: )

exten => s,n,SET(CALLERID(name)=hidden)

exten => s,n,SetCallerPres(prohib_passed_screen)

line 1 needs to say

exten => s,1,SipAddHeader(P-Asserted-Identity: <sip:${CALLERID(number)}>)

I will give that a go!
