[Freeswitch-users] ZRTP not being detected?

Hi,

I have latest master built from git on Debain 7.
I have CSipSimple client with ZRTP enabled and why I try calling the ZRTP
enrollment extension (9787), FS tells me that my client doesn't have ZRTP
even though I can see in the logs that it does indeed see the ZRTP hash:

[DEBUG] sofia.c:8293 sofia/internal/1000 at my.domain.com receiving invite
from 85.xx.xx.xx:58163 version: 1.5.12b git f50f04b 2014-03-28 18:33:47Z
64bit
[DEBUG] switch_core_media.c:343 Found audio zrtp-hash; setting
r_sdp_audio_zrtp_hash=1.10
35928c6c5064434bac6ba255ac970c28387c31c5adb1997e2df248623f042123

Looking at the zrtp_agent.lua script I see
 session:getVariable("zrtp_secure_media_confirmed_audio");

However, the extension "is_zrtp_secure" in the features context mentions a
slightly different variable <condition
field="${zrtp_secure_media_confirmed}" expression="^true$">

Can this be the root of the problem, ie the mismatch between
"zrtp_secure_media_confirmed_audio" in the lua script and
"zrtp_secure_media_confirmed" in the fetaures context?

What's the proper variable terminology to use here?

Any idea why FS doesn't seem to detect my ZRTP hash?

Cheers,

Peter
