|
|
* 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>
|
