[Freeswitch-users] ZRTP enrollment lua script question

[Peter Villeneuve]

Hi all,

I'm trying out the option to have FS play trusted MiTM for ZRTP.
I just compiled Master from Git and tried calling the 9787 extension from
my softphone with ZRTP.

I see in the dialplan that the script appears to get executed, however I
don't hear anything at all and after a little while the call hangs up.
It's not a codec issue because calling the IVR works fine.

So, what else do I need to do to allow ZRTP enrollment?

I see in the wiki that I need to set <action application="set"
data="zrtp_enrollment=true"/>
So how do I set this globally so that FS always negotiates ZRTP with
enabled clients? Or do I need to set that up in the dialplan?
