Bandyer Web Communication Center

The Communication Center allows the creation of a new channel that will facilitate the adoption of our technology within existing systems. The Communication Center creates a configured channel to forward all calls notifications and alerts. The latter regard all calls activities made by users - using the integrated technology - such as calls invitations, alerts of busy users and so on.

How Bandyer Communication Center works?

The Bandyer Communication Center makes possible to create a Call between two or more participants. The client who initiate the call is called initiator. The call initiator creates the call specifying the participants.

import CommunicationCenter from '@bandyer/web-communication-center';
var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');
BandyerCommCenter.connect()

The initialize method returns a CommunicationCenter object. Note that calling the method does not connect the SDK to Bandyer Servers. You must call the method connect.

Start a call

var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');
await BandyerCommCenter.connect()
BandyerCommCenter.call(['user_fake_1', 'user_fake_2'], {})

Once the SDK is connected to the Bandyer server, you can initiate a call using the .call method. You must specify an array of participants and valid options for the call.

Handle incoming call

Once the SDK is connected, it fires events regarding the calls. One of the most important event is the incoming_call event. The incoming_call event handles the incoming call request from the server. For example:

var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');
await BandyerCommCenter.connect()
BandyerCommCenter.on('incoming_call', function(call){
	// call contains a call Object with all the relative methods such as answer,reject and hangUp.
	// For example: call.answer() || call.decline(declineReason) || call.hangUp(stopReason)
})

Answer a call

To answer a call, use the answer method in the Call object. The Call object is available either as a data in the incoming call event or from the global object using the .getCall(roomAlias) method. For example:

var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');

// 1st method
await BandyerCommCenter.connect()
BandyerCommCenter.on('incoming_call', function(call){
	call.answer();
}) 

// 2nd method
await BandyerCommCenter.connect()
BandyerCommCenter.getCall('rmn_fake_1234').answer();

Once you answered the call, the Call object will be decorated with the token to connect to the Room of @bandyer/web-core-av.

Decline a call

To decline a call, use the decline method in the Call object. The Call object is available either as a data in the incoming call event or from the global object using the .getCall(roomAlias) method. For example:

var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');

// 1st method
await BandyerCommCenter.connect()
BandyerCommCenter.on('incoming_call', function(call) {
	call.decline();
}) 

// 2nd method
await BandyerCommCenter.connect()
BandyerCommCenter.getCall('rmn_fake_1234').decline();

Events

The communication center object fires the following events:

Event	Description
incoming_call	Fired when you are receiving a call
call_dial_answered	Fired when a user answers to the ongoing call
call_dial_declined	Fired when a user declines to the ongoing call
call_dial_stopped	Fired when a user stops to the ongoing call
user_connected	Fired when a user connects to the Communication Center
user_disconnected	Fired when a user disconnects from Communication Center

incoming_call

The incoming_call event is fired when the communication center receives an incoming call for the user connected. The incoming_call event contains the Call object decorated with all the data required to connect to the room.

var BandyerCommCenter = CommunicationCenter.initialize('user_fake_1', 'wApp_fake123456789', 'sandbox');

await BandyerCommCenter.connect()
BandyerCommCenter.on('incoming_call', function(call) {
	// Call object 
}) 

call_dial_answered

The call_dial_answered event is fired when the communication center receives an answer response related to the ongoing call. For every user who answer the call, you will receive the call_dial_answered.

call_dial_declined

The call_dial_declined event is fired when the communication center receives a decline response related to the ongoing call. For every user who decline the call, you will receive the call_dial_declined.

call_dial_stopped

The call_dial_stopped event is fired when the caller hangs up the call during the dial action.

user_connected

The user_connected event is fired when a user of your company connects to Communication Center.

user_disconnected

The user_disconnected event is fired when a user of your company disconnects from Communication Center.
