How to get websocket enabled API ?
Looking to integrate web socket.
Does it possible with current version ?
Try checking Kamailio SIP server. It has great support for websockets needed for webRTC. You can also try upgrading to Asterisk 11.20 which also has webRTC. As a side note, when you upgrade to Asterisk 11.20, you need to upgrade Vicidial to the latest SVN version.
