Yate as a Conference Server
Yate allows you to build your own application on his functionality as a Server of conference.
Yate as a conference server can be customized as needed and also you can build your own function.
Yate allows you to make an external script that can create conference on demand. Also you can write a scheduler to call all participants to a conference.
Among conferences capabilities are:
- - play announcements
- - mute/unmute a participant
- - record the call
- - add/remove a participant from conference
- - bill the participants
A conference can be started from different places, directly from routing module or from an external script or by using module Pbxassist, that has the capability of doing PBX operations for conference on receiving DTMF sequences.
Create a conference from routing module
A simple conference can be executed via regexroute.conf. Choose a number that will join people in a conference:
^800$ = conf/sampleroom;lonely=true;billing=true;maxusers=200
Here 800 will join people into a conference which is limited to 200 users, and where if there is only one person, they will remain in it.
Create conference using external script
You can make your conference in two ways:
1. By letting the users call a specific number
2. By making a scheduler that will call all the participants to join the conference room
Either way here are some steps to follow, to create your conference from an external module.
The parameters that are needed for conference room are taken from call.execute and call.conference messages.
In the script you can check the identity of the caller from the database and if he has a conference scheduled then send him to conference room, else you can play him a prompt to say that he hasn't a conference at that moment.
To make a conference from an external module:
$m = new Yate("chan.masquerade");
$m->id = "";
$m->params["message"] = "call.execute";
$m->params["id"] = $partycallid;
$m->params["callto"] = "conf/cs-$conference_id";
$m->params["notify"] = "conf-monitor/cs-$conference_id";
$m->params["billing"] = "true";
$m->params["lonely"] = "true";
$m->params["maxusers"] = $maxusers;
$m->params["smart"] = "t";
if ($is_organizer == "1") {
$m->params["record"] = "external/nodata/conference.php";
// set this so that script can play warnings in conference
$m->params["recordwarn"] = "-";
$m->params["speakers"] = $speakers;
$m->params["interval"] = $interval_notifications;
$m->params["waitlock"] = -200;
} else {
$m->params["existing"] = "t";
}
$m->Dispatch();
