[Freeswitch-users] Mod_Conference ESL: Filtering Events

Tue Feb 12 11:50:17 MSK 2013

Hey All,

So I found the solution to my problem and I'm updating the wiki page for
event filters so it might help someone else too.

Here's what I did:

$con->events("plain","all");
$con->events("plain","CUSTOM conference::maintenance");
$con->sendRecv("filter Unique-ID $uuidMember1");
$con->sendRecv("filter Unique-ID $uuidMember2");
$con->sendRecv("filter Unique-ID $uuidMember3");
.
.
.
Do this for all conference members in your script, say in a loop or
something, and then you'll get all custom events, pause/unpause,
started/stopped speaking, all in a single script.
