I found a video on how to unmask hidden Caller ID's:

The code used in this video is:


--extensions.conf

[inbound]
exten = 1208*******,1,Playback(silence/1|noanswer)
exten = 1208*******,2,Set(passertedid=${SIP_HEADER(P-Asserted-Identity)})
exten = 1208*******,3,Set(privheader=${SIP_HEADER(Privacy)})
exten = 1208*******,4,GotoIf($[${LEN(${privheader})} > 1)?8)
exten = 1208*******,5,Set(CALLERID(all)=${CUT(passertedid,8,1):5})
exten = 1208*******,6,Dial(SIP/1805*******@flowroute)

exten = 1208*******,8,Set(CALLERID(all)=+900${CUT(passertedid,8,1):5})
exten = 1208*******,9,Dial(SIP/1805*******@flowroute)

--done
