That is just what the channels <https://github.com/englercj/node-esl/tree/master/examples/channels> example of node-esl is doing. It basically dumps the changes in a channel to the client to update a list that the client maintains (the server also buffers the changes, but that is because the example demonstrates 3 different methods of displaying the data). -Chad From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Mumuney Abdlquadri Sent: Wednesday, October 31, 2012 6:55 AM To: freeswitch-users@lists.freeswitch.org Subject: [Freeswitch-users] application synchronisation between freeswitchand web Hi all, I am think of building an application like the demo here http://www.certificall.net/Try I noticed that the calls are in complete sync with the app. I am thinking to use ESL (maybe node-esl) and tunnel the events through socket.io.
