Video Conferencing

Google Talk Adopts Jingle As Default VoIP Protocol

June 24, 2011


Google has adopted Jingle as the default protocol for Google Talk. Jingle is an extension of the XMPP which allows for peer-to-peer and session control (signalling) for multimedia interactions such as VoIP and videoconferencing.

The protocol was developed by Google, Collabora, Yate, Tandberg and Jabber Inc. Others that support it include Asterisk, FreeSWITCH, Nimbuzz, and Pidgin. Imagine a P2P protocol that lets the thousands of Asterisk-based PBXs to communicate with each other using XMPP. Taking the Asterisk ecosystem along with other large user bases from Nimbuzz, Google Talk, and potentially others could potentially build the largest P2P VoIP / video conferencing network in the world. Bigger than Skype.


Google Building Skype-like App in the Browser

June 22, 2011


Look out out Skype, Google Chrome is looking to add voice & video capabilities to the Google Chrome browser. Shortly after releasing WebRTC audio and video chat software as open-source, Google has begun to integrate WebRTC into Google Chrome. They're leveraging Global IP Solutions (GIPS) for the VoIP and video codec pieces. As you know, GIPS used to be the packet loss concealment and VoIP codec used by Skype before Skype dropped them in 2006. Google acquired GIPS in May of 2010.

Gmail currently has audio and video capabilities but it requires the use of a proprietary plug-in, so it can benefit from this as well.

Blue Jeans Network Bridges Skype, SIP, H.323 for Multipoint Telepresence Solution

May 9, 2011

Blue Jeans Network has been quietly developing a new cloud-based video conferencing and collaboration service that bridges H.323 and SIP end-points, PSTN — and even Skype, with the goal of allowing users to connect everything from high-end video telepresence systems like Tandberg/Cisco and Lifesize to web cams running Skype to desktop IP videophones from Polycom, Grandstream, Cisco, and others. This solves a major problem with video conferencing and telepresence since interoperability, while it has improved, still doesn't take into account legacy H.323 end-points or users that only have inexpensive webcams. Blue Jeans Network plans to support Google and Microsoft Lync as well. Their cloud-based service handles the transcoding of audio and video codecs as well as manages the meeting IDs, PINs, etc.

Kaspersky Kills Microsoft Lync - No Audio or Video

May 3, 2011

If you use Kaspersky with Microsoft Lync (or OCS 2007), you may be interested to know that Kaspersky can kill Lync's connectivity. Specifically, Kapersky Internet Security's network traffic monitor, called Web Protection in some versions blocks the network traffic. It can kill remote desktop sharing sessions (Microsoft Live Meeting sessions) within OCS/Lync, as well as audio/VoIP, and video. Curse you anti-virus!

Skype for Android Exposes Personal Info

April 15, 2011

If you use the Skype for Android app your personal information may be vulnerable due to the way the app stores your data unencrypted and without proper file permissions.

Android Police reports that this exploit was discovered while checking out a leaked version of Skype Video on the Thunderbolt.

I quickly came up with an exploit, and I was in shock at just how much information I could harvest. Everything was available to the rogue app I created, without the need for root or any special permissions."

The HTML5 Revolution

April 14, 2011

When Steve Jobs and Apple blocked Adobe Flash from Apple's popular line of mobile devices (iPhone, iPad, iPod touch), Apple's main claims against Flash were that it was too processor-heavy, a battery hog, and that HTML5 was a better standard for the future. Rich Tehrani calls it the "Apple Tax". According to the HTTP Archive project, a website that tracks over 17,000 top websites and lets you compare web statistics over time, Flash experienced a 2% drop in usage over the last 4 months. It went from 49% on November 15, 2010 to 47% on March 29, 2011.

The move to HTML5 is clearly on.

Microsoft OCS QoE Voice Analyzer App for WP7

April 12, 2011

Are you a Microsoft OCS 2007 R2 or Microsoft Lync user looking to analyze the Quality of Experience (QoE) on your Window 7 (WP7) phone? Then I have just the utility for you! The QoE Voice Analyzer app is now available at WP7 Marketplace for download and it sports some nifty QoE tools.

It's worth pointing out that QoE metrics are collected at the end of every VoIP and video call from participant endpoints, which includes Office Communicator, Office Live Meeting, the A/V Conferencing Server, Mediation Servers and IP phones. The metrics are collected and sent in a SIP header to the OCS Front-End server by each client.

This WP7 app assists OCS admins to better understand the Microsoft 2007 R2 QoE reports.



WorldGate Ojo is <strike>Dead!</strike> <strike>No It Lives!</strike> Nope-Dead Again

April 6, 2011


I reported troubles at WorldGate Communications back in February 2008 and then reported things got better in the next month saying Ojo Phone Lives! It appears they never truly got through its problems, because their return of the living dead now appears to be over...


According to Rich Tehrani, "Word has it that funding was pulled at WorldGate Communications two weeks ago with everyone being laid off. Requests for information to the company did not get an immediate response. The Pennsylvania-based organization which made high-end designer-looking videophones no-doubt faced an uphill battle competing with Cisco and Polycom - as well as low-cost players like Grandstream."

It's pretty sad that a really cool video phone which had such promise wasn't able to cut it.
