Free and open WebRTC for the Fedora Community

In January 2014, we launched the service for the Debian community. An equivalent service has been in testing for the Fedora community at

Some key points about the Fedora service:

PostBooks 4.7 packages available, xTupleCon 2014 award

I recently updated the PostBooks packages in Debian and Ubuntu to version 4.7. This is the version that was released in Ubuntu 14.10 (Utopic Unicorn) and is part of the upcoming Debian 8 (jessie) release.

A URI prefix for radio callsigns

I've had my amateur callsign far longer than I've had my email address or provider-independent IP ranges.

While working with the tel: URI recently, I started thinking it would be useful to have a similar URI scheme for radio callsigns. After all, callsigns follow a well documented and globally unique pattern. Amateur operators are often mixing computing technology with radio. This could be a useful foundation for bigger things.

reConServer for easy SIP conferencing

In the lead up to the release of Debian wheezy, there was quite some debate about the Mumble conferencing software which uses the deprecated and unsupported CELT codec. Although Mumble has very recently added Opus support, it is still limited by the fact that it is a standalone solution without any support for distributed protocols like SIP or XMPP.

Best real-time communication (RTC / VoIP) softphone on the Linux desktop?

The Debian community has recently started discussing the way to choose the real-time communications (RTC/VoIP) desktop client for Debian 8 (jessie) users.

Google Summer of Code opportunities in JavaScript, HTML5, jQuery and WebRTC

WebRTC is one of the highlights of HTML5. The latest stable releases of Google Chrome (including the free Chromium browser) and Firefox include support for this technology and although the specifications are still being finalized, this is the time when developers can start preparing the first generation of web-apps that will define the future of this technology.

Free communications software takes another big jump

One of the most exciting demonstrations at FOSDEM this year was the new JitMeet web application from the Jitsi team.

JitMeet takes the power of the traditional Jitsi Videobridge and makes it accessible to anyone, anywhere (with a modern web browser) using WebRTC.

Debian SIP without reading the manual

Most people don't have time to read manuals. The Debian SIP service has a reasonably thorough user guide with screenshots but some people may just want to have this level of detail if they really have to troubleshoot a problem.

WebRTC is the fastest way to start

Just set up your RTC password and use it to log in to the site.

If you thought systemd proponents were bad....

Just imagine for a moment if something like the iPhone App Store approval process was applied to every application for a domain name. Delays and unexplained rejections killing many great ideas before they even get off the ground. In the worse cases, like that of Greg Hughes, the great firewall of the app store has been used to quash ideas that it appears Apple may have been planning to compete with or copy.

Lumicall: giving you choice when you dial

One of the distinguishing features of Lumicall, the free and open SIP/VoIP app for Android, is the unique dialing experience.

In fact, even regular softphones for the desktop/laptop don't currently offer the same power when you want to make a call.

In my previous blog, I looked at the ENUM technology that underpins part of this compelling new user experience. Here we can step back and look at the bigger picture.
