Graves On SOHO Technology

We have invited the folks from Twelephone to appear as guests on the VUC call Friday, December 28th. If you’ve not heard of them, Twelephone is a new video calling service built using WebRTC and effectively leveraging Twitter as namespace. It’s just one of many new web communications applications arising from from the newly evolved WebRTC standard.

Chris Mathieu is the founder of the project. Chris has appeared on a number of VUC calls in the past. Chris has long been involved with telecom related APIs, including spending some time worth with the Voxeans who created Tropo.

This is the fourth installment in the long-running tale (parts one, two & three) of my search for the most appropriate host for this site.

The very fact that you’re reading this means that the site is now live on a server operated by Lightning Base. In the past I’ve used a shared host and couple of different VPS providers. In point of fact the site was at UnmeteredVPS.net for over two years.

I have nothing but nice things to say about UnmeteredVPS.net. That service is excellent, but it wasn’t exactly a perfect fit. It was an unmanaged VPS, which meant that I was responsible for everything.

Every few weeks I would need to update some aspect of the OS or supporting software. Some updates were trivial. Some, like major Apache or MySQL updates, were a bit scary. Despite five years running this site I’m no Linux guru.

Last week I received a question via email from reader Marshall Wilgard. It seems that he is having trouble with a Grandstream BT-200 desk phone.

For five years, I used a Grandstream BT-200 IP phone without any problems.  Six weeks ago, a loud hum appeared on the phone as soon as I picked up the handset.  About 10 days later, the hum vanished, for no apparent reason.  However, about 10 days after that, the hum came back, for no apparent reason.  Despite my rebooting the phone three times, the hum remained.  Then approximately 10 days after the hum returned, it vanished again, for no apparent reason.  My phone has had the latest firmware for more than a year, and my VoIP provider says the problem is not with it.

Hum like Marshal describes is usually an analog phenomenon, not something that I’d associate with firmware. It sounds to me like a problem with the hardware. Issues of hum tend to revolve around a problem with the power supply. Given the age of this phone I’d guess that most likely some kind of capacitor is failing.

This week saw an announcement about the release of Ekiga v4.0. This is the most significant release of the venerable open source soft phone in some time. It brings with it many improvements.

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.

Some months ago I was doing some work around the house at the request of my wife. I can’t remember what exactly, but it involved some woodworking. The process was not going as well as I might have hoped and I was getting tired.

Somehow I managed to mash my hand, which aside from being painful brought the effort to a premature end for the day. My wife decided that we need to make a trip to our local Lowe’s anyway, and that I should take a break come along for the ride.

While at the store we stumbled upon a display for the Nest Learning Thermostat. A few days before I had mentioned to Stella that it was being rolled out nationally. I also told her a bit of the story about the company, its founder and their legal entanglement with Honeywell.

Upon seeing the device offered in the store, and with feelings of guilt stemming from my damaged digits, she bought the Nest as a thank you for undertaking her honey-do list.

The story of Nest is very appealing to her sensibilities. A small start-up shaking up a stodgy business, complete David v Goliath legal cases. Who isn’t drawn to an underdog? Especially when the product bears all the hallmarks of design by Apple .

Hey, here’s a semi-geeky gift that they’re sure to get a charge out of…a high-current  USB charger built into a common household receptacle. You may recall that I installed a couple of the FastMac USockets some time ago. There’s one at each of our night-stands, conveniently providing power to charge phones and tablets as we sleep.

At the time these things were comparatively rare so I ordered them directly from FastMac. Given my past history in construction and renovation I was able to install these myself. However, the fitting the USocket into the outlet box wasn’t the easiest thing to do. The USockets depth made it difficult to fit the wiring back into the box. I ended up replacing the box with a deeper one in the end.

While on a visit to our local Lowe’s I recently found that they have a similar product made by Cooper. These sell for around $20 and may be more conveniently available to you.

Like the USockets, they replace the existing outlet so you’re going to need to have some facility with tools in order to get them installed. They come in the Decora style so you may need a new cover plate. I see that Amazon has them In several colors, too.

If you’re not so handy with tools around electricity you might consider this alternative from RCA , also found at Lowe’s. For only $15 this one features quick, tool-less installation. It’s designed to plug directly into the existing outlet. Once installed the device sticks out about 1/2” from the wall.

Unlike older USB chargers, all three of these devices provide enough current to satisfy a tablet or high-end smart phone.

I like the fact that these device can’t go missing simply because someone needs to charge something else at the other end of the house. I especially like the fact that I no longer need outlet strips everywhere to accommodate all the chargers.
