[Freeswitch-users] Have someone zrtp with correct sas ?

[J.B. BERLIN]

Hi Michael,

thanks for reply where the difference in the configuration ?

How is the right configuration for bypass and what for MiTM ?

I build FS like so:

sudo git clone git://git.freeswitch.org/freeswitch.git
cd /usr/src/freeswitch
sh build/buildzrtp.sh
sudo ./bootstrap.sh
sudo ./configure -C --prefix=/opt/freeswitch --enable-zrtp --enable-64
sudo make all install sounds-install moh-install

Than put : global_setvar zrtp_secure_media=true in the conf

and following in my dailplan:

<!-- install zrtp_agent.lua into scripts (ZRTP == 9787) -->
      <extension name="zrtp_enrollement">
        <condition field="destination_number" expression="^9787$">
 	<action application="answer"/>
 	<action application="lua" data="zrtp_agent.lua"/>
        </condition>
      </extension>I can call 9787 and it’s say me that the call is secure but if I callanother user i become different SAS...?Kind regardsJacek

Is media flowing through FreeSWITCH? If so I think that FS needs to be configured as a "trusted man in the middle." The other option would be to bypass media and see if that works. I would start with the bypass media since that is the low-hanging fruit.

  Dear users,

  I try run FS last git build from today 19. June 2011 with ZRTP.

  Zfone show me green but the sas are everytime different!

  Tested with 2x Notebooks on Fedora 14 Twinkle(via yum) & with two desktops with Win7 x64 / Zfone 0.92.build.219 and X-Lite on both sides.

  FS is build with libzrtp-0.81.514

  zrtp.lua is enabled !

  global_setvar zrtp_secure_media=true" is set

  Or have someone a real good step by step guide ?

  Many thanks and best regards
  Jacek
