Hello! We are bridging calls in *bypass-media* mode with profile parameter *<param name="media-option" value="resume-media-on-hold"/>* ... <action application="set" data="bypass_media=true" /> <action application="privacy" data="yes" /> <action application="bridge" data="{...}sofia/external/+ 12223334455@10.10.10.10" /> ... So initial origination INVITE on B-leg has Privacy: id and PAI headers - everything works as expected. But if a user on A-leg presses Hold button, re-INVITE (without SDP) on B-leg (corresponding to the option *resume-media-on-hold*) will not have privacy headers. And this leads to disclosure of caller anonymity on some phones. On the picture below I marked re-INVITE (B-leg) that has no Privacy and PAI.
