> My upstream provider complained that Anonymous calls to our endusers got de-anonymized during transit in our platform. These incoming calls have the headers:
> {quote}
> From: "Anonymous" <sip:anonymous at anonymous.invalid>
> {quote}
> and
> {quote}
> Privacy: id;user;critical
> P-Asserted-Identity: "Example" <sip:0123456789 at example.org;user=phone>
> {quote}
> After passing through Asterisk 13.14.x, the Privacy header is removed, PAI is unaffected and From is changed to:
> {quote}
> From: "Example" <sip:0123456789 at example.org;user=phone>
> {quote}
> All involved pjsip endpoints have send_pai, trust_id_inbound and trust_id_outbound set to yes.
> This violates RFC 3233:
> {quote}
> Privacy-hdr  =  "Privacy" HCOLON priv-value *(";" priv-value)
>    priv-value   =   "header" / "session" / "user" / "none" / "critical" / token
> {quote}
> Where:
> {quote}
> critical: The user asserts that the privacy services requested for
> this message are critical, and that therefore, if these privacy
> services cannot be provided by the network, this request should be
> rejected.  Criticality cannot be managed appropriately for
> responses.
> {quote}
> But is RFC 3323 still applicable to SIP?
