Skype Journal wrote about one of the coolest mashups I've ever seen. Certainly one of the coolest VoIP mashups. Skype Journal explains PhoneFromHere Tim Panton's demo that he gave at Astricon where Tim mashes up Google Wave, Skype, Asterisk running Skype for Asterisk and Ibook to make Skype calls from within a browser-based Google Wave.


Not only is it sans Skype client, but it has recordings (labeled by person speaking) of individual utterances, so you can quickly playback what a particular person said at a certain point in time.

It's amazing to make a Skype call from a browser without running the Skype client. How do you ask? Well, it uses a browser-based Skype client using a IAX2 Java client to communicate with Asterisk which then communicates with the Skype network cloud. On top of it all you get Google Wave's powerful collaboration capabilities.

Perhaps some IP address geocoding combined with Google Maps to show the speakers' locations might be nice addition to this mashup. Or even pulling down Facebook profile pictures. There is definitely some awesome potential for this. Maybe Google can even stick your Google Wave/Skype/Asterisk collaboration sessions into their newly released, centralized, Borg/hive, data-collecting, privacy-busting Google Dashboard?

Ribbit today announced the release of Ribbit Mobile, a free communication suite designed for mobile professionals who need to be able to easily manage all of their phone numbers, communication devices, and how & when they are contacted.

Ribbit Mobile is a cloud-based service that lets you manage calls, messages and phones. It's hard not to compare this new offering to Google Voice. One advantage of Ribbit Mobile is that it can make calls from within your browser using their Flash-based software client. Ribbit Mobile features include voicemail transcription, smart call routing, and web-based calling. During the introductory (beta) period, Ribbit is making their "Professional" package free.

Since it leverages Ribbit's open VoIP platform, it can even call your Skype, MSN or Google Talk account, as well as SIP devices. Additionally, when a new voicemail arrives, Ribbit can notify you via email, Google Talk, Skype, or SMS. Ribbit Mobile transcribes voicemail to text and sends it to you via SMS and email. It also provides a web portal inbox where messages can be managed and stored forever. No voicemail retention limit which is nice.

Ribbit Mobile also has something they like to call "Caller ID 2.0" which links your Ribbit contacts address book with your contact's Facebook, Twitter, LinkedIn and Flickr accounts. You can see recent updates made by your contacts to their social networks and pictures of your contacts as seen here:

Today, Microsemi is launching a new line of midspans which feature integrated lightning protection. This marks the first time a PoE midspan features lightning protection. As more and more PoE devices are used outdoors, including outdoor wireless Access Points (APs), outdoor security cameras, and more, having lightning protection is critical. One lightning bolt strike and it can wipe out your entire networking and IT infrastructure. While lightning is great & all since it bestows Captain Marvel his super powers, when it comes to networking equipment, not so much.

The new PowerDsine 9001G-40/SP is a single-port, high-power Gigabit solution for remotely powering both current and emerging high-power networking terminals and equipment while also providing surge protection optimized for outdoor devices such as security cameras and wireless LAN access points.


                 Rear product view

According to Microsemi, "Until now, PoE could only be deployed safely outdoors with a costly surge-protection unit installed alongside it, to prevent direct or nearby lightning strikes from damaging or destroying both the powered devices and their network switch. Surge and lightning protection units can cost from $250 to $400."

"A high percentage of outdoor PoE installations, especially in the enterprise, do not implement surge protection units because of their high cost or a lack of awareness," said Sani Ronen, senior product manager for Microsemi's PowerDsine midspans. "Nearby lightning strikes are much more common than most people think. Strikes as far as a mile away can induce a voltage level that can damage outdoor devices. Without lightning protection, surges also can move quickly along the Ethernet cable to damage expensive indoor network switches. Our new midspan delivers that protection at a cost savings of as much as 50 percent."

Microsemi's newest midspan has been tested successfully to the GR-1089 lightning standard for surges up to 2500V/500A. It can power devices designed for either the IEEE 802.3af standard, or the recently ratified IEEE802.3at standard for high power over Ethernet applications.

The 9001G-40/SP offers up to 40W of power which means it can support power-hungry devices such as 802.11n access points, pan-tilt-zoom cameras and WiMAX customer premises equipment.

"The 9001G-40/SP was designed to deliver the latest benefits of the new high-power 802.3at standard while also offering a cost-effective, single-box solution for powering and simultaneously protecting outdoor PoE systems from lightning damage or destruction," Ronen said.

KEY FEATURES
- Interoperability with IEEE802.3af and IEEE802.3at devices
- Lightning protection up to 2500V/500A
- 10/100/100-BaseT support

Pricing and Availability
The PD-9001G-40/SP Midspan is available in production for a unit list price of $119. Additional information is available at Microsemi's website here: http://www.microsemi/PowerDsine.com.

If you're running Office Communications Server or LCS whatever you do, don't install KB974571 or you will cause the LCS or OCS server to state you are running the evaluation version and then say it has expired. Poof! - There goes your corporate unified communications (UC) followed by a parade of your coworkers carrying pitchforks & torches looking to find out why their UC isn't working. How widespread this patch is affecting OCS/LCS installs worldwide is unknown.

KB97451 is also known as  "MS09-056: Vulnerabilities in CryptoAPI could allow spoofing" and it was released just yesterday on Patch Tuesday. If you use WSUS or Windows Update to automatically download/install patches, you might be surprised this Wednesday morning to find your OCS/LCS server has failed. Didn't we have Patch Tuesday cause another major outage? (See: Skype Outage & Skype Outage caused by Windows Update)

If you apply the patch, the LCS/OCS services fail to start and you see these errors in the event log:

Event Type:        Error
Event Source:    Live Communications Server
Event Category:                (1000)
Event ID:              12290     
Description:
The evaluation period for Microsoft Office Live Communication Server 2005 has expired. Obtain the released version of this product and upgrade to the non-evaluation version by running setup.exe

Uninstalling the patch is the only way to fix it. According to the Microsoft OCS blog, "The issue is currently being escalated, but until a fix can be found, delaying the install of KB974571 is recommended."

The big news last week was how AT&T grants denies us mobile VoIP freedom. Just last week I wrote how AT&T had "granted" us mobile VoIP freedom by finally allowing SIP port 5060 on their 3G data network. I was able to use siphon, a SIP-based application on my jailbroken iPhone to register with TMC's IP-PBX and make/receive phone calls.

Well apparently, AT&T must read my blog or something, because once again SIP port 5060 is blocked. I tried siphon on my iPhone this morning and now it won't register. I tested port 5060 and it is indeed blocked. Alas, so no more SIP calls using siphon. The AT&T Overlord giveth, and the AT&T Overlord taketh away.

Hey FCC, can you give AT&T a little smackdown for me please? Just last week AT&T announced it was allowing VoIP over 3G, so why the inconsistency? Is it because siphon is a jailbroken app and not an "official" iTunes app?  I doubt it. I doubt AT&T is able to detect what iPhone application is making an outbound connection. That would be a form of spyware if AT&T knew exactly which iPhone applications you were using. So seems to me that AT&T is still blocking VoIP calling over their 3G data connection. AT&T is talking a big game about being "open", but they aren't backing it up. I'm sure they'll blame it on some network glitch or something. AT&T could be dragging their feet on allowing VoIP over their 3G network hoping the mere "huge" announcement of support for VoIP over 3G will get the FCC off their backs. It's time for the FCC to stop AT&T's stalling tactics. I want my mobile VoIP freedom and I want it now!

On September 17th I wrote about how siphon, a SIP app for the iPhone was working over 3G for me in Los Angeles but not in Connecticut. Apparently, port 5060, the SIP port was blocked in Connecticut but not in Los Angeles. Sources have informed me that AT&T was trialing opening up port 5060 nationwide but was first opening it up in select cities, including Los Angeles. I guess I was onto the "big news" about AT&T now allowing VoIP over 3G calls and didn't know it.

I just tried siphon again in Connecticut, which just a few weeks ago was not working, and whaddya know? It works! I was able to register an extension to my Asterisk-based IP-PBX and make an intercom call to my coworker. Quality was superb over the 3G data connection. I was also able to receive a call. Since my iPhone is jailbroken, I was able to set siphon to run in the background and receive inbound calls while checking my email. Sweet! Being able to make and receive SIP calls on the iPhone is certainly a game changer.

Here's a screenshot of me connected over 3G. I blurred out TMC's SIP server for obvious reasons:


Of course, it isn't just SIP VoIP calls that work over 3G now. Before AT&T's announcement to allow VoIP over 3G, Skype was limited to just WiFi but now it too works over 3G. Allhough there were "hacks" to get around the WiFi limitation by using VoIPover3G or 3G Unrestrictor. I've been using these hacks for awhile to make Skype over 3G calls. Guess these hacks are no longer needed. Though Skype will have to release a new software update to allow VoIP over 3G calls. By default it tells you it isn't allowed. This also means all the other SIP-based applications in the Apple App Store will have to release new versions that remove the 3G restriction. It might take some time for your favorite VoIP app to be released that allows 3G data calls, but it is coming.

So what does this mean for mobile VoIP? Well, AT&T has just opened the door for iPhone users to use inexpensive SIP termination service providers of their choice. Of course, most mobile phone users already have a free bucket (3500, 5000, etc.) of minutes, so this may not mean much to them. The big deal may only come into play when making expensive international calls. Then again, teenagers can use 3500 minutes in a week, so having a supplemental service (VoIP over 3G) that can help them avoid overage charges could be huge for the teenage demographic.

Lastly, businesses will find it useful because now employees can have a single-number identity. Coworkers can just dial a fellow coworkers extension and it can ring their iPhone over 3G. No need to know the cell phone number, which the coworker may wish to keep private anyway. Although there are some complexities involved with having a desktop phone and an iPhone registering simultaneously with the same SIP credentials for an extension. Vonage solved the dual SIP-credentials dilemma, so I'm sure the IP-PBX manufacturers will figure it out as well. Outbound single-number identity works beautifully as well. Now employees can make calls using the CallerID of the corporation and not their iPhone's phone number, thus retaining the privacy of their cell number.

Finally AT&T has granted us mobile VoIP freedom... So I have one last thing to say...
F R E E D O M !!!!


Update 10/12/09:
Apparently, AT&T must read my blog or something, because once again SIP port 5060 is blocked. No more SIP calls using siphon. The AT&T Overlord giveth, and the AT&T Overlord taketh away.

The 10th Anniversary of the AstriCon 2009 conference is next week in Arizona (October 13-15) and it is shaping up to be a great show. For one, AstriCon is sporting 30% more companies in the Expo Hall than last year's conference. The AstriCon organizers have even thrown in some cool freebies to add to your Asterisk arsenal.  All attendees receive three popular Asterisk licenses, including: Skype for Asterisk, Fax for Asterisk, and G.729 for Asterisk.

AstriCon 2009 will be held at the Renaissance Glendale Resort and Spa near Phoenix, Arizona. You can register for the conference at www.astricon.net.

Today Vonage launched Vonage Mobile for the Apple iPhone and Blackberry. I've already said this will be a killer app and could sway iPhone users to sign up with Vonage. Though, many iPhone users and wireless phone users in general have killed their landline entirely. Nevertheless, there are some cool features with Vonage Mobile, including a single-number identity for both your home and mobile number that could give Vonage an added boost.

Vonage World is not limited to just WiFi - it works over 3G!  Vonage Mobile offers low-cost international calling and Vonage claims that you can save more than 50% on calls to dozens of countries versus the rates charged by wireless carriers. Vonage Mobile will be available for download on the iPhone, BlackBerry and iPod touch at www.vonage.com and the iTunes App Store later today.

In Q42009, Vonage will enhance the app to include the popular Vonage World plan that was introduced recently. "Vonage World" includes unlimited calling across the world to over 60 countries, which covers 2/3 of the world's population (4.5 billion) all for just $24.99/month.

"Our new mobile app is an important step in establishing Vonage as a software technology company that enables high-quality voice and messaging across any device in any location, providing great value over any broadband network," said Marc Lefar, CEO of Vonage.

Vonage Mobile features:
• Rates are better than traditional wireless and landline carrier rates
• Lets you make calls while on Wi-Fi or cellular networks, providing full mobility
• Uses your existing contact list - just click and dial - no extra steps
• Utilizes your existing cell phone number so the people you call will recognize who is calling
• Real-time balance updates and the ability to automatically replenish funds in your account
• No more trips to the store to buy calling cards, no 800 numbers or access codes, and no connection charges

What an inglorious end to the Verizon Hub, which Verizon Wireless promoted as the greatest VoIP phone ever. Sure it was sexy, and sure it was gadgety - doubling as a Web tablet and digital phone frame, but apparently users just weren't buying. Not even a year after Verizon Wireless launched the Hub they have killed it.

Verizon Wireless said Sept. 30 it was discontinuing sales for its Verizon Hub. The Hub retailed for $199 and required a $34.99 monthly fee. Too high a price if you ask me. What they should have done is sold it for $50, but lock customers into a 2-year contract or something to offset the costs of this phone device. If they terminate early, then you charge them full-price. Verizon Wireless should know this pricing model from their cellphone plans. But who am I to give financial lessons?

RIP Verizon Hub, we barely knew you...
