WebRTC your FreeSWITCH

Posted on May 20, 2014 by

We harp on about Unified Communications quite a bit. One of the new up-and-coming technologies regarding UC is WebRTC. WebRTC can put click-to-call capabilities within reach of web developers without needing any plugins and instant audio communication within reach of end-users without even needing to take their attention away from your site.

WebRTC-FreeSWITCH

While still in the process of being widely adopted, WebRTC is already supported by several major browsers (Chrome, Firefox, and Opera). And for your back-end, WebRTC is now baked into the current active development branch of the open source FreeSWITCH communications platform.

Enabling WebRTC in FreeSWITCH in a supporting version is as straightforward as adding a single line into your relevant internal SIP profile of your FreeSWITCH config (I tacked it onto the end of sip_profiles/internal.xml to make all internal SIP profiles usable via WebRTC). Here is the magic maker:

<param name="ws-binding" value=":5066"/>

So enabling it is a total cinch. Recompiling FreeSWITCH 1.5.12b from scratch, and setting the ws-binding, I was able to get WebRTC calls working like a charm.

Now depending on your usage and comfort with beta software, you can have a WebRTC FreeSWITCH server up and running today. If you’re using FreeSWITCH for your PBX system and click-to-call tickles your fancy, it might be advantageous to start your dabbling now, so when WebRTC support is finalized in a stable release, you’ll be on board already.
