Revisiting The Merits Of Battery Backup

According to a FierceTelecom article by Sean Buckley, “Verizon says fewer customers are purchasing battery backup for fiber home voice services.” The article describes how Verizon’s FiOS FTTH customers are tending to rely upon their mobile phones to stay on touch during a power outage.

This assertion comes right as the FCC is concerned about CPE remaining powered during an outage, something that cannot be done over fiber as it was over copper. Since customers were not buying traditional battery backup units Verizon has come up with its own solution called PowerReserve.

Polycom VVX Series & USB Headsets

I love when things “just work.” This happens so rarely as to be noteworthy. What follows is a nice example with respect to my Polycom VVX-600 and a USB-attached headset.

This afternoon a plaintive beep in my ear told me that the battery on my Sennheiser DW Pro2 cordless DECT headset was nearly depleted. This when I still had a lot of my working day left. Looking across the room I saw a wired headset that I have been evaluating for some ZipDX applications. It was a Passport 21P Headset, fitted with a Plantronics DA40 USB Digital Adapter.

Interconnecting Jitsi Video Bridge, ZipDX & YouTube Live

In the production of over 530 VUC sessions we’ve undertaken some odd and occasionally rather complicated arrangements. Quite possibly the most complex is when we interconnect the WebRTC-based Jitsi Video Bridge with YouTube Live and the ZipDX conference bridge. I set about described aspects of this process a year ago, but stopped short of describing how the entire arrangement worked. Well, worked most of the time. This article will bring you current with my various attempts to make this process robust and repeatable.

Preface: When we use Jitsi Video Bridge we lose a couple of the conveniences that come with a Hangout-On-Air. Where a Hangout-On-Air has an automatic link to a YouTube Live event, we must do this manually when we use JVB.

#VUC540: Tim Panton Presents YoPet – A WebRTC Application

yopet-logo-360pxVUC540 on Friday, May 8th, 2015 will feature Tim Panton, WebRTC guru, VUC regular and self-described protocol droid, detailing a recent pet project known as YoPet. YoPet is a WebRTC-based service built to allow pet owners a simple, secure way to video chat with their furry, scaly and/or feathered friends.

Yopet is comprised of a web service that connects the distant pet owner back to the home, where the pet has access to an Android device running the YoPet application. In the telling of this tale Tim will illuminate a variety of issues faced in developing the app & associated service.

This weeks related form of dangerous demo may involve one of my canine office-mates demonstrating YoPet live.

As Randy is taking a vacation in Cuba, where internet access is extremely limited, I get to be pilot-in-charge for this little online misadventure. Now everyone please be seated, it could be a little bumpy on the climb to cruising altitude. Fear not, the unflappable Andy Smith of TruePhone will be in the co-pilot seat.

Review: Algo Communications 8028 SIP Door Phone

The necessity of a gate bell in my working life stems from the combination of a fenced yard and a home office located well in the back of the property. The lack of such capability at the front gate makes receiving deliveries chancy, often requiring a lengthy drive to a UPS or Fedex facility to pickup a missed delivery.

In researching our initial attempt to remedy the lack of a gate alert I learned about SIP door phones from several companies. These devices were targeted at very large homes or office and apartment buildings, and tended to be very costly. Most were well over $1,000, which was dramatically beyond my budget.

However, Algo Communications offers a SIP door phone for a single family dwelling with a list price around $500. At the time I had thought that something analog, for around $250, was a better option. While that choice kept me on budget, it was ultimately disappointing, most especially when the device failed outright.

Wide Range Audio Meters

simple_vu_meter_by_masaakikaji-d47vzp9It has been said that anything that can’t be measured, can’t be managed. While there’s some debate about the universality of this statement, it’s most definitely true for audio levels.

With respect to the independent measuring of audio within a computer I’m please to share a new software tool that I’ve recently been using; Wide Range Peak Meters by Darkwood Designs.

Before I get into the application and it’s capabilities you might like to know why I think it’s necessary. To be over simplistic, WebRTC!

What I really mean by that is PC-based audio handling by soft clients that lack their own audio metering.
