+chan_sip
+-----------
+ * SIP peers can now specify 'trust_id_outbound' which affects RPID/PAI
+   fields for prohibited callingpres information. Values are legacy, no, and
+   yes. By default, legacy is used.
+   trust_id_outbound=legacy - behavior remains the same as 1.8.26.1. When
+     dealing with prohibited callingpres and sendrpid=pai/rpid, RPID/PAI
+     headers are appended to outbound SIP messages just as they are with
+     allowed callingpres values, but data about the remote party's identity is
+     anonymized.
+     When sendrpid=rpid, only the remote party's domain is anonymized.
+   trust_id_outbound=no - when dealing with prohibited callingpres, RPID/PAI
+     headers are not sent.
+   trust_id_outbound=yes - RPID/PAI headers are applied with the full remote
+     party information in tact even for prohibited callingpres information.
+     In the case of PAI, a Privacy: id header will be appended for prohibited
+     calling information to communicate that the private information should
+     not be relayed to untrusted parties.

+
+	* Asterisk 11.9.0-rc3 Released.
+
+	* chan_sip: Add sendrpid trust options
+
+	  In r411189, some behavior was changed which made sendrpid behavior
+	  act in a more trusting manner by sending full user data for peers
+	  set with private caller presence in P-Asserted-Identity headers.
+	  Since this changed long time expected behaviors, we decided to pull
+	  that patch when that was pointed out by the community. Instead, this
+	  patch provides a trust_id_outbound setting which will expose the data
+	  per RFC-3325 if set to 'yes' and simply not send the PAI/RPID headers
+	  at all if set to 'no'. By default trust_id_outbound will be set to
+	  'legacy' which will preserve the behavior prior to these patches.
+	  Extra special thanks to Walter Doekes for providing advice and
+	  feedback.
