Evolving The Mobile Data Billing Model

AT&T 3G USB DongleEarlier this week AT&T has its quarterly earnings call. Normally I would not give it any notice at all. It’d just be another bunch of noise in my Google Reader in-box. This week they did something that simply jumped out at me; they called for an evolution of the current billing model for mobile data plans. Oddly enough…I agree…sort of.

Of course, their perspective on this is not quite the same as my own. AT&T want to be rid of the $60/mo for all-you-can-eat billing model and charge based upon actual usage, perhaps in some sort of tiered fashion.

Literally everyone knows that the current billing model is badly broken. Their flat rate “unlimited” plans are not really unlimited at all. My Sprint 3G service was pretty plain about it being capped at 5 GB/month. Beyond that I’d guess that it gets costly. Moreover they claim performance levels that almost no-one ever achieves in practice.

Amazon Responds About SIP Attacks From EC2

On April 18th Amazon finally responded publicly with respect to the SIP attacks recently suffered from hosts within their EC2 service. Their response comes in the form of an informational security bulletin posted to their AWS Security Center.

There have been some recent discussions about SIP brute force attacks originating from Amazon EC2. We can confirm that several users reported SIP brute force attacks originating from a small number of Amazon EC2 instances about a week ago. It appears these attacks were designed to exploit security vulnerabilities in the SIP protocol. There is nothing specific about this attack that requires Amazon EC2. It was a brute force attack that could be launched from any computer on any network.

Video Conferencing & Volcanic Ash

The volcanic eruption in Iceland, and its associated ash cloud, has certainly been a major topic of discussion this past week. My brother and his wife were caught in France on vacation. Their two week skiing vacation has become three weeks, quite unexpectedly.

Further, while we were focused on the NAB convention in Las Vegas three of my UK-based associates ended up extending their stay in the US by over a week, unable to get flights home. I suspect that I’m not the only one wishing that we had pushed forward with our plans to install room type video conference systems in Cambridge and Burbank. Those systems would certainly have been very handy this week.

Gigaset’s New DX600A Small Business Phone

Earlier this month Gigaset launched the DX600A, a new model of desk phone targeting the small business and home office. In North America this went largely unnoticed as the DX600A is currently only available in Europe, and specifically in an ISDN capable model.

Since ISDN lines are extremely uncommon in North America the DX600A in its present form doesn’t apply to that market. However, I’m told that there’s a chance that a SIP capable version of the device could be introduced in the US if there are signs of demand. On that basis I think that the DX600A is worth a closer look.

The HP Mini Twins

I've been toying with my new HP Mini 5102 for a couple of days. It'll take a little longer before I can get into the details of it, but it's a nice little machine. Here's a pic of the Mini…

One Week Using Clear 4G In Las Vegas

I spent last week in Las Vegas working through the annual convention of the National Association of Broadcasters (NAB) annual convention. This was my 18th NAB convention. It’s my one annual trek to the desert.

This time I took advantage of the time in Las Vegas to try Clear‘s newly launched 4G network. Fellow VoIP blogger Andy Abramson connected me with people at Cheetah Wireless, a Clear reseller, who offered a special price on the short term rental of a 3G/4G USB dongle. Since recently launched 4G service in Houston I was especially interested to see how it differed from the 3G service that I’ve had via the Sprint Mifi these past months.
