Hi folks,
I would like to show a project my colleage José Luis Millán and me are working on. It's about SIP protocol running in a web browser. When RTCweb (media capable web browsers) becomes a reality both technologies together will allow real SIP endpoints coded in JavaScript running in a web browser and interoperating with real SIP networks. Bye bye Flash and custom protocol gateways.

Cheers.

I think this is awsome. If I understand this right, this is based on your SIP over websocket draft, which basically adds a new transport to SIP. So for Kamailio, we would need a new transport.

Right. All this stuff is based on a new transport for SIP: WebSocket. This transport is a bit more exotic as it not a layer 4 transport (WebSocket is a transport layer built on top of TCP/TLS, and it's a message boundary transport as UDP or SCTP).
This is really awesome.
Is any of that stuff on the video open to play with?
(I know it does not support audio but the SIP chat aspect is really great.
Thanks.

Not yet, but it will be.

It's based on SIP MESSAGE. Implementing MSRP will be the next step :) For audio/video we must wait for RTCweb to become an standard.
Thanks a lot.
Cool; I will wait until the code is available.
If I understand what I saw correctly you have implemented a JS SIP stack which runs native in the browser over web-sockets.

Yes, it's a JavaScript code implementing a full SIP stack (parsing, transactions, dialogs...) and uses a WebSocket connection for sending/receiving SIP requests/responses.
There is also in the picture a SIP proxy implementing the WebSocket transport, if not, the JavaScript client could not interoperate with SIP networks ;)
Regards.
inaki,
i read your slides and have question about the example: is OverSIP sip proxy still needed if Kamailio sip proxy/registrar would implement websocket transport?

No, it isn't. But OverSIP is not just a proxy providing WebSocket transport ;)

i would prefer not to add more servers into my sip platform, because there is already sip proxy, registrar, presence server, xcap server, msrp server, and sems that provides several services. hopefully yours would replace some of those rather than add yet another one.

I plan to add a MSRP relay server on top of OverSIP (MSRP over TCP, TLS and WebSocket, still to be defined) and also plan to build a presence server, but not a SIMPLE/XCAP presence server, a new specification instead:
Cheers.
