-- the switch natively supports ZRTP itself.
--

--
-- <extension name="global" continue="true">
-- <condition break="never">
-- <action application="lua" data="lua/zrtp_proxy_media.lua"/>
-- </condition>
-- </extension>
--
-- If any particular call flow should never have proxy_media enabled,
-- such as for connecting to voicemail systems or conferences, make
-- sure this is called before the bridge:
--
-- <action application="lua" data="lua/zrtp_proxy_media.lua disable"/>
