[Freeswitch-users] ESL Mod_Conference Observations

[Usama Zaidi]

Hey,

Looks like I found a solution to this one as well, and turns out ESL is
MUCH more powerful then I thought, I've updated the wiki page for filters
if anyone wants to have a peek
http://wiki.freeswitch.org/wiki/Mod_event_socket#filter

Short answer, filter Conference-Unique-ID $ConfUUID
