Web browsers don’t allow signaling for WebRTC to run over non-secure transports. That means you can only use HTTPS or secure websocket. So… if you want to use SIP as your signaling towards the browser, you’ll need to do it as SIP over a secure websocket.

The other option is to translate SIP to something else in a gateway and then use HTTPS or secure websocket.

Muhammad,

There are several alternatives out there. You can use Pusher, PubNub and even Firebase to do this. You can install your own SimpleWebRTC or AppRTC signaling. You can use Matrix.org. …

In most cases a SIP signalling gateway will not be enough since WebRTC implements DLTS based SRTP for media encryption and this is now commonly supported in legacy SIP systems. You need consider a signalling gateway with media proxy functions like TekSIP.

In reply to Lio. Lio, If you have no development experience, I suggest you hire a team that does. Check the WebRTC Index for some suggestions. If you need consulting on who and how to build it, then this is what I do. Alternatively, you can check out my WebRTC API platforms report (requires payment). It has the various alternatives for both development tracks and vendor selection.

In reply to Andrew Prokop.

Andrew,

That’s a good question. I now tend to split it into two parts, based on something Justin said about this some time ago – I have mixed here both Signaling and Transport protocols.

On the Transport side, it is either HTTPS, HTTP/2 or Websocket now (where HTTPS further splits off into COMET types)
On the Signaling side, it is either SIP, XMPP or proprietary

I’ll be writing something about it soon – just because you asked this question 🙂

How do you feel about this two years later? Would you add anything new? Would you take anything off the table?

In reply to Nick Jennings.

Nick,

Using the data channel for signaling means building a distributed layer where browsers communicate among themselves assisting each other to find their destination.

You can use a signaling server using WebSocket to connect to this distributed layer and continue all negotiations from there. I’ve seen this discussed more than once in the past.

There’s also the part of having the initial connection handled by a signaling server but any further communication go over the data channel.
