<div dir="ltr">You can't set the zrtp_secure_media=true after a session is created, it needs to be a global or you set it inside the {} on the bridge or originate line. Then you're outlining uuid_media off, which would make the media go between the two endpoints, FreeSWITCH isn't even involved in the zrtp exchange at that point. Technically your endpoints should be the ones doing this and ZRTP should be disabled in FreeSWITCH, You really only need ZRTP with MiTM if you MUSt transcode or you're terminating directly on the FreeSWITCH instance. I should really just rip out MiTM support.</div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Feb 10, 2015 at 5:53 AM, Peter Steinbach <span dir="ltr"><<a href="mailto:lists@telefaks.de" target="_blank">lists@telefaks.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Hello,<br>
<br>
I want to establish ZRTP, after I am bridging 2 calls, which have
been active already before.<br>
<br>
My scenario is as follows:<br>
<ul>
<li>Caller A is calling Freeswitch, the call is answered and an
announcement is played</li>
<li>In the meantime Freeswitch calls another Party B and connects
it to an internal IVR, where also announcements are played.</li>
<li>Now, after a while, I decide to connect the calls together,
then send an "uuid_media off <uuid>" to the calling party
A leg, reinvites occur and bypass media works.</li>
<li>However the 2 SIP clients (Csipsimple) do not start a ZRTP
session</li>
<li>If caller A calls B directly via bypass media, the ZRTP is
active, by the way.<br>
</li>
</ul>
<p>I suspect that ZRTP somehow should be forced or triggered. Is
there a way to do that? I already invited the B leg with "zrtp_secure_media=true"
and issued</p>
<p> uuid_setvar 1bd508af-19c7-4e38-8621-731baaf33920
zrtp_secure_media true<br>
uuid_media off 1bd508af-19c7-4e38-8621-731baaf33920<br>
to the A leg. But this did not work.<br>
</p>
<p>The main question should be: How can I trigger a ZRTP connection
on an existing call?<span class="HOEnZb"><font color="#888888"><br>
