June 01, 2006, at 06:54 PM by paulc -
Changed lines 25-26 from:
to:
  • recordwarn (default empty) allows specifying an override source for the recording channel so that the participants are warned
Changed lines 31-32 from:
to:

A call.conference without a channel can be used to control recording. A record parameter that is "off" or "false" or "disable" will stop recording, else the old recorder is stopped and a new one created.

April 17, 2006, at 01:32 PM by paulc -
Added lines 5-11:

The name of the conference room to connect to depends of the message:

  • for call.execute the callto parameter must be of the form "conf/NAME" (default empty) sets a specific room name, if the NAME is empty a new, unique conference room name is generated
  • for call.conference the room parameter (default empty) sets a specific room name instead of generating a new, unique one

In both cases the actual name of the conference is returned in the room parameter as "conf/NAME" like it should be used for further references.

The automatically generated room names are of the form "x-NUMBER" where NUMBER is incremented for each new room created. You must never make assumptions about the next room number, you must use the returned room parameter.

Deleted line 12:
  • room (default empty) sets a specific room name instead of generating a new, unique one

Conference room module

The conference room is an N-way audio mixer to which an arbitrary number of conference legs are attached.

Each conference leg has the following capabilities that are controlled by the parameters of the call.execute or call.conference message:

  • room (default empty) sets a specific room name instead of generating a new, unique one
  • existing (default false) forces using an existing room else the call fails
  • smart (default true) computes energy and supresses noise
  • echo (default false) hear back own voice in the conference's global mix
  • voice (default true) can speak to the conference, else can only hear it
  • utility (default false) creates a housekeeping conference leg that is not counted with regular users
  • billing (default false) emits messages needed to bill conference participants

The conference room itself has a set of capabilities that are taken from the parameters of the message that created the room:

  • maxusers (default 10) sets a limit to the number of users that can join a room
  • lonely (default false) allows the conference room to persist even when there is only one user connected
  • record (default empty) allows specifying a route that will make an outgoing record-only call
  • notify (default empty) enables generating notification messages for conference events

Messages

The conference module handles two messages:

  • call.execute creates or attaches to an existing conference
  • call.conference creates a conference from an existing call allowing to add more call legs to it

Besides the normal channel messages the conference rooms can generate chan.notify messages with the following parameters:

  • targetid - ID of the notification requestor
  • event - name of the event that created the message - "created", "destroyed", "joined" or "left"
  • room - name of the conference room
  • users - number of users currently in conference (only for "joined" or "left" events)
  • caller, called, billid, username - only for the "created" event

Configuration

There is no configuration file for this module. All parameters are taken from the call.execute or call.conference message.
