* Manages a list of all the currently active calls.
|
|
*
|
|
* This handler dispatches when voip calls are added/updated/removed from this list:
|
|
* {
|
|
* action: 'call_state'
|
|
* room_id: <room ID of the call>
|
|
* }
|
|
*
|
|
* To know the state of the call, this handler exposes a getter to
|
|
* obtain the call for a room:
|
|
* var call = CallHandler.getCall(roomId)
|
|
* var state = call.call_state; // ringing|ringback|connected|ended|busy|stop_ringback|stop_ringing
|
|
*
|
|
* This handler listens for and handles the following actions:
|
|
* {
|
|
* action: 'place_call',
|
|
* type: 'voice|video',
|
|
* room_id: <room that the place call button was pressed in>
|
|
* }
|
|
*
|
|
* {
|

* action: 'incoming_call'
|

* call: MatrixCall

*
|

* {

|
* action: 'hangup'
|
|
* room_id: <room that the hangup button was pressed in>
|
|
* }
|

|
|
* The conference handler is a module that deals with implementation-specific
|
|
* multi-party calling implementations. Riot passes in its own which creates
|
|
* a one-to-one call with a freeswitch conference bridge. As of July 2018,
|
|
* the de-facto way of conference calling is a Jitsi widget, so this is
|
|
* deprecated. It reamins here for two reasons:
|
|
* 1. So Riot still supports joining existing freeswitch conference calls
|
|
* (but doesn't support creating them). After a transition period, we can
|
|
* remove support for joining them too.
|
|
* 2. To hide the one-to-one rooms that old-style conferencing creates. This
|
|
* is much harder to remove: probably either we make Riot leave & forget these
|
|
* rooms after we remove support for joining freeswitch conferences, or we
|
|
* accept that random rooms with cryptic users will suddently appear for
|
|
* anyone who's ever used conference calling, or we are stuck with this
|
|
* code forever.
