Building on my previous work to put convenient WebRTC solutions into the hands of the free software community, I've just created the DruCall WebRTC module for Drupal.

DruCall makes it easier than ever to put click-to-call functionality into virtually any Drupal powered web site, whether your run a personal blog or the United States Government (the White House really does use Drupal)

People wishing to deploy DruCall will need a WebRTC (SIP over WebSockets) capable SIP server. Both the major SIP proxies have this capability now in their development versions:

• repro / reSIProcate WebRTC support, just check out and compile the b-webrtc branch
• Kamailio WebSockets support, also see Peter Dunkley's blog for more details

Big thanks to the developers of SIPml5 for providing a full SIP over WebSockets client in JavaScript that is used as the foundation for the DruCall project
