In 2013 Dr. Schulzrinne was inducted into the Internet Hall Of Fame. The following clip is his acceptance speech from that ceremony. I offer it in the hope that it will help inspire some good questions.
The technical part of this weeks exercise will involve the use of Jitsi Video Bridge (http://jitsi.org) to host the call instead of our usual G+ Hangout. Thus we’ll be taking a pure, open source, WebRTC approach to things. Given a limited number of seats on the Jitsi video bridge they are by invitation only.
To allow more people to watch the call the Jitsi Video Bridge feed will be live streamed to our YouTube channel*. http://youtu.be/-pfXBE2POxo
Jitsi Video Bridge has a newly implemented ability to dial out to a SIP URI. This is how we’ll be interconnecting with ZipDX. Since both JVB and ZipDX support the Opus codec that will be a good quality connection.
Interactive, if audio-only, participation in the call will be possible by connecting to ZipDX via SIP URI (firstname.lastname@example.org)
The article describes how he published the script used to run the exploit. That allowed others to try the exploit against various makes/models of consumer hardware. It thus came to light that the same trick works against various products from Linksys and Netgear, amongst others.
I’m especially interested in the following new capabilities:
New audio codecs: SILK (used by skype), G.722.1 (aka Siren 7), G.722.2 (aka GSM-AMR Wide band)
Video codecs changes: H.264 optimizations
Added RTP TOS support
Support for DNS SRV caching
While developed primarily on Linux Ekiga has long supported multiple platforms. I took a short while today to try the new release on an older Windows XP laptop. The Windows installer also installed the GTK libraries necessary to support the application. Installation was quick and painless.
If you were keeping an eye on the realm of open source PBX offerings you might be lulled into thinking that there is Digium with Asterisk and Switchvox, then everyone else. Where “everyone else” was basically hobbyists and Freeswitch fanatics. Well, that’s easy to understand, but you’d be wrong. I know that I was.
I’m not familiar with either of the Broadcom codecs. I see that they are available in some versions of Counterpath’s X-Lite and Eyebeam soft phones. Support for these codecs in hardware is something that I’m yet to determine.
One project that I’m am about to start is moving from my m0n0wall router to a new one build around pfsense. The motivation for the project is the integration of our Comcast Business Class internet service into the rest of the household. At present there are two separate networks, with only a few devices enjoying the high speed cable service. The pfsense system will be configured for dual WAN, accessing both the cable service and Covad DSL circuit.
My existing m0n0wall runs on an old Soekris Net4801. In service for many years, it has been extremely reliable. If m0n0wall does what you need I have no hesitation in recommending the software. Support from the user community is tremendous as well.
