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 


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


added following line to 


   <!--<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

Were you being literal when you said to type in zrtp on the phones keypad? I 
assume you meant dial the phone number equivalent to that.

I also assume this is not working because 
1) I should put the zrtp_agent.lua script in one of the designated script 
dirs like 

    <!-- <param name="module-directory" value="/usr/lib/lua/5.1/?.so"/> -->
    <!-- <param name="module-directory" value="/usr/local/lib/lua/5.1/?.so"/> 


2) I need to wait until zfone3 is released and recompile FS with the new tar 
file from the zfoneproject site


3) both of the above apply?
