As subject. It will provide SIP service like ekiga.net, sip2sip.info,iptel.org. Main difference is that it will support websocket. So you can use your browser to login.
In first phase, you can only register and make a call to another SIP endpoint. It will not support presence, chat, and another advanced features. I will add it when there are many requests to add it.
Disclaimer : i'm relatively new to SIP (+- 7 months) but i have strong interest in it. So, there is a chance that the server still unstable in the beginning. I promise to do my best to provide good server.
