Adding a valid SIP address emits error

[npafitis]

Trying to create a connection using this library this way

this.janusClient = new Janus.Client('sip:my-domain.com:5060');
    this.janusClient.createConnection('some_identity')
      .then(connection => {
        console.log(connection);
      })
      .catch(err => {
        console.log(err);
      });

and i get this error:

DOMException: Failed to construct 'WebSocket': The URL's scheme must be either 'ws' or 'wss'. 'sip' is not allowed.

Any help would be appreciated.

Hi there,

I have clarified the basic usage example in the README.

1. Make sure to have a Janus server running - including WebSocket support (see https://github.com/meetecho/janus-gateway/blob/master/README.md)
2. Connect to your janus instance, e.g.:

var janus = new Janus.Client('ws://localhost:8188', {
  token: 'token',
  apisecret: 'apisecret',
  keepalive: 'true'
});
