[asterisk-users] INVITE Privacy Information

[Cyprus VoIP]

Thank you Philipp for your help.

I ran into this problem: When I change the CALLERID(num and name) to 
anonymous, they are also changed in the RPID line and not only in the From.

This is the script:
exten => _*67.,1,SIPAddHeader(Privacy: id);
exten => _*67.,2,Set(CALLERPRES()=prohib_passed_screen);
exten => _*67.,3,SIPAddHeader(P-Asserted-Identity: 
<sip:${CALLERID(num)}@10.10.10.20:5060>);
exten => _*67.,4,Set(CALLERID(num)=anonymous)
exten => _*67.,5,Set(CALLERID(name)=Anonymous);
exten => _*67.,6,Dial(SIP/${EXTEN:3}@10.10.10.10)

... and this is the result:
INVITE sip:0011223344 at 10.10.10.10 SIP/2.0
