[Freeswitch-users] ESL Mod_Conference Observations

13 Feb 2013


      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

Subject: [Freeswitch-users] ESL Mod_Conference Observations
Hi,
Just wanted to know why don't I get any events on start/stop speaking
conference joins/leaves if I do something like this:
$con->events("plain","all");
$con->events("plain","CUSTOM conference::maintenance");
$con->sendRecv("filter Unique-ID $confUUID");
Instead I've to do something like this:
$con->events("plain","all");
$con->events("plain","CUSTOM conference::maintenance");
$con->sendRecv("filter Unique-ID $confmember1");
$con->sendRecv("filter Unique-ID $confmember2");
$con->sendRecv("filter Unique-ID $confmember3");
.
.
.
Which is useless in case you want to check if a user is entering/leaving a
particular conference in a single inbound ESL script...
What I'm doing instead now is something on these lines:
$con->events("plain","all");
$con->sendRecv("filter Unique-ID $CONFNAME");
i//psuedocode
if event equals PRESENCE_IN and presence-call-direction equals inbound then
{
    execute API command conference list confname
    parse uuid from members add a filter update the hashtable for existing
confmembers
}
//once we have the uuid filter added we'll get to know if that user
leaves, so the logic for removing the filter is straight forward
if event equals CUSTOM and subtype is CONFERENCE::MAINTANANCE
{
    if event action=del-member remove filter for UUID
}
I don't get ANY event if I'm filtering on conference UUID... I think that
needs to be fixed, because its mod_conference which is throwing all those
events.
Regards.
