tryit-jssip's Introduction

tryit-jssip

The JsSIP demo application.

Check it online at https://tryit.jssip.net

Installation

Fork the project.
Install dependencies:

$ npm install

Globally install the NPM gulp-cli package:

$ npm install -g gulp-cli

Build the app (check the gulpfile file for details):
- gulp prod generates the app in production/minified mode.
- gulp dev generates the app in development mode.
- gulp live generates the app in development mode, opens the local website and watches for changes in the source code.
Once built, the out/ directory is created with all the HTML, CSS and JavaScript files to be deployed in your own server.

Hardcoded settings

The app allows entering settings via an HTTP form in the Login section. However, the developer can hardcode some specific settings (for example the callstats.io settings) by defining a window.SETTINGS variable before the tryit-jssip.js is loaded.

Check the commented code in the index.html and fill it as needed.

Notes

If you run this web application into your own domain, you will also need to set your own SIP/WebSocket servers. The SIP servers running at the public demo won't accept connections origins other than https://tryit.jssip.net.

tryit-jssip's Issues

npm install fails

I tried to follow the installation instructions, but 'npm install' failed. Did I do make some stupid mistake (I don't know much about npm)? I was not able to find ibc/react-notification-system from github.

Hi,Versatica:
I run this demo, cannot call others, while establishing a call ,it always return sip failure code.
When I click the button call ,it wait to establishing a call , but when it connect to other phone ,it close the connection immediately, and return sip failure code.My account is right, I has do a right call with sip.js .

Error: User Media Defined Access

Hello!
I'm having some problems when i try to start a call from Browser to Browser

I got error : User Media Defined Access
The Browser console logs :

Note: I have provided microphone phone setting to always allow

No video on incoming call

I'm trying to accept video call (alaw/h264) with tryit demo app. I can answer the call and audio works fine, but there is no video. App says "no remote stream". However, everything works fine if i test it on demo clients provided by sipml5 and sip.js. This is relevant for official installation (https://tryit.jssip.net) and for my own checkout of jssip-tryit. I really like jssip and would glad to use it further. Where should i dig from here to fix this problem? i would appreciate any advice. Thanks in advance!

npm install failed after upgrade to Debian 11

I upgraded my host OS from Debian 10 to 11 and noticed that npm install does not anymore succeed. I got

From page https://www.npmjs.com/package/react-addons-css-transition-group I learned that now react-transition-group is recommended as react-addons-css-transition-group replacement. So I went and in package.json replaced line

with line

"react-transition-group": "^4.4.2"

and in lib/components/TransitionAppear.jsx line

import ReactCSSTransitionGroup from 'react-addons-css-transition-group';

with line

import ReactCSSTransitionGroup from 'react-transition-group';

After that npm install worked (with lots of depreceted warnings):

window.SETTINGS deepmerge fails

I removed comments from index.html window.SETTINGS (below) and after that I get to console error:

tryit-jssip:settingsManager window.SETTINGS found +0ms tryit-jssip.js:6775:4
TypeError: can't assign to property "arrayMerge" on true: not an object umd.js:75

It works if I replace the deepmerge stuff with simple assignment:

if (window.SETTINGS) {
  logger.debug('window.SETTINGS found');
  // settings = (0, _deepmerge.default)(window.SETTINGS, settings || {}, true);
  settings = window.SETTINGS;
} // If not settings are found, clone default ones

My window.SETTINGS look like this:

			window.SETTINGS =
			{
			display_name        : 'Test',
			uri                 : 'sip:[email protected]',

Old tryit app

Hi,

Could you create a repo or branch with the old tryit app please?
We were using it with an internal Turn server and the new app is missing Turn configuration.

Thanks

Configuring STUN/TURN servers

Hello guys,

How can I configure the STUN and TURN servers. Not sure what is the format and also I need to set the credentials for turn. So far what I have is:

iceServers : [ { urls : [ 'stun:myserver:19302' ] } ]

Can advise how to set the TURN with credentials, thank you so much in advance.

Hello
First of all thanks for writing this beautiful demo using jssip , I have a problem with the time this webrtc client takes to initiate a call, so I read the jssip documentation and I found a event related to this
http://jssip.net/documentation/3.2.x/api/session/#event_icecandidate

so how I can implement this into the webrtc client? I'm appreciate for any help on this issue.
I want to reduce ice gathering time out to 3-5 second actually.
Best regards
