I've got 1.0.4 running with zrtp on ubuntu 9.0.4. I have 3 zrtp capable
endpoints: an xp desktop running ekiga with the 0.92 build 218 zfone client,
2 cell phones running ver 2.0.5 of the Tivi softphone: a nokia e61i (symbian
s60) and an O2 Xda Flame (windows mobile 5).

All 3 endpoints are registered with FS using the default extensions of 1000-
1003

With global_setvar zrtp_secure_media=true the zrtp negotiation between end
points happens but the SAS never matches,below is console output for a call
between 2 of the endpoints

Of note, with the endpoints registered through the Ekiga sip server, the sas
DOES match on both ends.

With global_setvar zrtp_secure_media=false, the endpoints can't detect a zrtp
peer.

Reading the list archives hasn't enlightened me.

I see this comment from 2008

This is because you didn't install the zrtpagent.lua script and dial
zrtp on your keypad to enroll the FS box as a trusted man in the
middle... which btw will only work with the unreleased zfone3.

Brian, okay, that answers the case with FS acting as a trusted man in the
middle, but what about in the peer to peer case? Shouldn't FS just be passing
the ztrp traffic through to the endpoints? Or am I misunderstanding how it's
supposed to work?

Secondly where would I find info about zrtpagent.lua? Doing a search for that
term on the wiki returns no results, ditto for a search of the nabble list
archives (other than your response today of course). Also ditto for a search
of the box running FS.

I can confirm that it works 100% correct passing the SAS across the
bridge correctly once you trust the switch in the middle.

They have a trial version of the full client available from their website, I
think it's only for 10 days though. I suspect if you approached them, they'd
probably give you a full client for permanent use for interoperability
testing.

Opps, my bad, it's only for 3 days

You can bid on the price you want to pay if you are into buying a copy.

Just got the word back from them, the 2.0.6 client is available for Windows
Mobile but not officially released since it has some issues with video
encryption. Since I'm not using video yet, I am going to upgrade the windows
mobile phones with this version.

So I popped the zrtp_agent.lua script into

/usr/local/freeswitch/scripts/

added following line to

/usr/local/freeswitch/conf/autoload_configs/lua.conf.xml

<!--<param name="startup-script" value="zrtp_agent.lua"/>-->

under this section

<!--
The following options identifies a lua script that is launched
at startup and may live forever in the background.
You can define multiple lines, one for each script you
need to run.

And restarted FS, when I try to connect and type zrtp on the keypad it
doesn't work and I see

If you reinstall the latest sound files you'll have them.

Ahh, I didn't quite clue-in that I had to run the additional installers as
below when the main compile finished, I thought it was saying it had already
done that.
