Now I want to allow callerid hidden calls if the UAC sends an INVITE with:

  From: "Anoymous" <sip:anonymous at anonymous.invalid>
  P-Preferred-Identity: "Iñaki" <sip:ibc at domain.org>
  Privacy: id

To authenticate this INVITE the proxy can't look for the domain in "From", but 
in domain of "PAI" header.

It could be nice if this would work:
  
  is_domain_local($(hdr(P-Preferred-Identity){uri.host})) {
    route(4)  ; Auth route
  }

But unfortunatelly it doesn't work since it's not a variable containing just:
  sip:user at domain
but:
  "Display name" <sip:user at domain>

so it's not possible :(

I'll open a feature request :)
