Fellow wideband enthusiast Steven Perich (@boxdog) just posted a review of the new Jabra M5390 Wireless headset. Based upon Bluetooth and supposedly wideband capable, he tried the version of the device that ships with a USB dongle for use with…
After thinking about 3G based mobile broadband for the past month, and suffering through another bout of paying for less than stellar access at hotels, Andy Abramson finally broke through the last of my resistance with a post about weekend Mifi deals on Amazon. I fell for the offer of the one cent Mifi device and decided on Sprint as the carrier.
As I mentioned earlier in the week I had been wanting to add the service to my T-Mobile account, since that where I have my cell service…and I’m happy with them. But many people told me that T-Mobile’s 3G network was not up to the task. Also, they don’t yet offer a Mifi-style device. That left Sprint and Verizon as my options.
Earlier this week Dan Berninger, CEO of the newly formed HDConnect trade group offered up another guest post on Jeff Pulver’s blog. In this post, entitled “Telecom Turnaround,” Dan outlines the decline in demand for traditional voice services over the past decade. He also hints at the typical arguments that nay-sayers offer against wideband telephony. It’s all good stuff.
There’s something that I’d like to add to what Dan puts forward. By whatever name it’s known, HDVoice, HD VoIP, or simply wideband telephony…improved call quality is only the beginning. When voice is just another application on an IP network there are a many advantages that can be realized. Improved call quality is just the first benefit that we’ll see (hear?), and possibly the easiest to sell both to the public and regulators.
In mid-July I traveled to the UK, visiting my employer’s head office in Cambridge. Being away from my home office is in some ways a drag. I’m so accustomed to being in control of my local network, which is certainly not the case when I’m abroad. Suffice it to say that I can’t use anything VoIP related from within the office LAN at HQ, with the possible exception of Skype.
At the hotel where we typically stay near HQ there is wired internet access provided by Swisscom. It’s a decent service, reasonably fast and reliable. However, at 15 Pounds Sterling (around $22 USD!) per 24-hour period it’s also very dear. To get around some of this cost one of my co-workers loaned me a company issued Vodaphone 3G USB dongle. This was the first time that I’d used one of these little gadgets.
Question: What was the first HDVoice product that Polycom offered?
Answer: The Polycom VTX 1000 conference phone.
The thing that makes this fact so curious is not immediately obvious. The VTX 1000 is not a SIP device, nor even IP capable. Like it’s closest relative the Polycom SoundStation 2, it’s designed to connect to a plain old analog phone line (a.k.a. POTS, the PSTN).
Of course, the common wisdom is that you just can’t have wideband telephony over the PSTN. Yet the VTX 1000, circa 2003, delivers wideband conference calls so it seems that assertion is not strictly true. Understanding this is in a little more depth would seem like a good thing. Happily, Polycom published a white paper describing the internals of the VTX 1000.
I can't recall where but someone recently asked me if the keypads on the Gigaset SIP/DECT handsets are backlit. At that very moment I didn't know, but I have since confirmed that all three (A58H, S67H and SL78) are in…
