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?<br>
</p>
