Connector Hyperty

The Connector Hyperty main functionality is to handle two party audio and voice conversations by using WebRTC technology. Main features:

– invite user for a WebRTC audio or video call

– accept/reject invitation

– have a cross domain video conversation with another peer eg

– interoperability with SIP / IMS User Agents as well as with any reachable public E.164 enabled Mobile or Fixed phone.

This Hyperty handles standard Connection Data Objects. Live Demo Hereto be provided.

API

The Connector Hyperty implements two Hyperty APIs to be consumed by Applications:

– the Hyperty Connector API manages the creation of new WebRTC connections;

– the Hyperty ConnectionController API manages a certain WebRTC connection instance.

Hyperty Connector API

The Hyperty Connector API is used to create new connections.

connect

This function is used to create a new connection providing the identifier of the user to be notified.

<Promise> ConnectionController connect( URL.UserURL user, MediaStream stream, string ?name)

parameters

user - user to be invited that is identified with reTHINK User URL.

stream - WebRTC local MediaStream retrieved by the Application

name - is a string to identify the connection.

returns

A ConnectionController object as a Promise.

How to use it

  connector.connect(user, stream, name).then(function(controller){

  // your source code

  }).catch(function(reason) {
      console.error(reason);
  });

onInvitation (addEventListener)

This function is used to handle notifications about incoming requests to create a new connection.

onInvitation(ConnectionController connection)

parameters

connection - the ConnectionController to handle the incoming connection invitation.

How to use it

connector.onInvitation(function(connection){...});

Hyperty ConnectionController API

The Hyperty ConnectionController API is used to control a connection instance.

accept

This function is used to accept an incoming connection request received by connection.onInvitation().

<Promise> boolean accept( MediaStream stream)

parameters

stream - WebRTC local MediaStream retrieved by the Application

returns

It returns, as a Promise, true in case the connection is successfully accepted, false otherwise.

How to use it

connection.accept(stream).then(function(accepted){

// your source code

}).catch(function(reason) {
    console.error(reason);
});

decline

This function is used to decline an incoming connection request received by connection.onInvitation().

<Promise> boolean decline(int ?reason)

parameters

reason - Integer decline reason that is compliant with RFC7231. If not present 400 is used. (optional)

returns

It returns, as a Promise, true in case the connection is successfully declined, false otherwise.

How to use it

connection.decline(reason).then(function(declined){

// your source code

}).catch(function(reason) {
    console.error(reason);
});

disconnect

This function is used to close an existing connection instance.

<Promise> boolean disconnect()

returns

It returns as a Promise true if successfully disconnected or false otherwise.

How to use it

connection.close().then(function(closed){

// your source code

}).catch(function(reason) {
    console.error(reason);
});

onDisconnect

This function is used to receive requests to close an existing connection instance.

onDisconect(DeleteEvent event)

parameters

event - the DeleteEvent fired by the Syncher when the Connection is closed.

How to use it

connection.onClose(function(event){...});

Descriptor

The Hyperty Connector descriptor is:

  "HypertyConnector": {

          },
          {
            "url": "turn:194.65.138.95:3478",
            "credential": "luis123",
            "username": "luis"

      },

      ],
      "accessControlPolicy": "somePolicy"
      }

The Hyperty Connector descriptor includes the required WebRTC ICE servers configuration:

"configuration": {
"webrtc": {
  "iceServers": [
    {
      "url": "stun:stun.l.google.com:19302"
    },
    {
      "url": "turn:194.65.138.95:3478",
      "credential": "luis123",
      "username": "luis"
    }
  ]
}
}

Since the Hyperty supports the standard connection data schema, any Catalog URL for that schema can be used.
