Plantronics MX500i 3-in-1 headset has superb sound

June 27th, 2008 No comments

Finally I’ve found the one headset I’ve been looking for that can serve as a PC headset and a handset/mobile phone headset.  I was pleasantly surprised by the Plantronics MX500i 3-in-1 VoIP Headset.  I figure at an MSRP retail price of $60, it had to be good but it was even better than I though.  You can actually get it for $38 including shipping.

The MX500i 3-in-1 is a product that has both a 2.5″ headphone plug that plugs in to most regular cordless telephones and a USB adapter that plugs in to any computer.  I’m happy to report that both operating modes worked superbly and the ear design works well and isn’t unwieldy.

I’ve had plenty of disappointments with USB or BlueTooth headsets which almost always seem to be limited to narrowband applications because they would only support 8 KHz digital sampling.  The Polycom Communicato C100S continues to be my favorite USB speaker phone solution ($100) can support 22 KHz digital sampling and it supports wideband applications such as Skype or Counterpath‘s software-based SIP phones which support G.722 wideband codec (see this article on an explanation of wideband codecs).

Hoping the Plantronics MX500i would at least match the Polycom’s capability, I was pleasantly surprised that it even supports up to 48 KHz digital sampling.  In fact it was louder and clearer than the Polycom Communicator speakerphone and I would dare say that it sounds about as clean as a studio microphone though it’s probably a little more constrained in dynamic range to filter out noise.  Here is an uncompressed WAV sample I recorded for you to check the quality.

If I had to give it one criticism, I would say that the USB adapter and headset along with all the cabling combined is a little harder to tidy up and travel with than the Polycom Communicator which tucks everything in to a neat little package.  Then again, the Communicator costs more than double the money and its sound quality while the best for a USB speakerphone can’t compare to this high quality headset.

So in conclusion, I would say this is an affordable solution that sounds even better than the Polycom Communicator though the Communicator is still useful for hands-free and ear-free operation.  If you’re looking for something in the $40 range or you’re looking for the best call quality, the Plantronics MX500i is for you.

Review of the Mitel 5340 IP Phone

June 25th, 2008 4 comments

Mitel 5340 IP telephoneI recently had the opportunity to take a look at one of Mitel’s latest devices, the 5340 IP telephone with an integrated Sun Ray 2 client. The device is part of their push towards unified telecommunications with the Mitel Unified IP client for Sun Ray. What is interesting to me about this phone is the linkages between the phone and the Sun Ray system, and the way that they have leveraged each device.

Setting up the unit was easy. In line with “typical business usage,” I did not look at the instructions at all, I simply started to plug up cables. My only stumbling block was trying to figure out why they seemed to give me an “Ethernet pass-through brick” that connected to power and at the same time why the phone would not come on. After a minute, I realized that the “Ethernet pass-through brick” was a PoE module; plugging that in got the device up and immediately usable. From there, it was 100% intuitive. Desktop support specialists can roll these devices out as fast as any phone. When the Sun Ray session started, it automatically detected my monitor resolution. Mitel let me know that the Sun Ray session needs to be restarted to adjust to a different monitor resolution if a differently sized monitor is connected, but other than that, moving to a different workstation if needed is a breeze.

The phone itself is a handsome unit in line with similar units that I have used. There were a few features which really stood out. The first item was the handset itself; the unit came with a cordless handset which included buttons for hang up, volume, and mute. The fact that it was a cordless handset was a pleasant surprise. My testing showed that it had a pretty reasonable range and solid voice quality; I could exit the building and walk over hundred feet down the road before I noticed any breakup. One thing that would be nice, is if the handset allowed the plugging in of a headset with a 2.5 mm jack; on the other hand, serious “phone warriors” probably already have a cordless headset that they are hooked on, so the cordless handset here is just gravy. The cordless handset can be programmed to connect to a central “switchboard” to perform dialing by voice, even though it does not have a keypad on it. 

The phone was quite usable, especially in comparison to other office phones that I have used. There are only a few buttons on it other than the keypad, and the marking on them make sense. When the “mute” button is used, it is quite clear that the phone has been muted (a bright orange light comes on). Transferring calls and performing conference calls is intuitive; anyone who has fumbled for ten minutes and dropped the conference call five times knows the pain that many of the phones have in using those two features! Accessing voicemail, establishing call forwarding, and so on was also extremely easy. Best of all, the on-phone help was simple to use, accurate, well worded (in plain, short text), and had depictions of the needed buttons that made it easy to follow along. Over all, I like the phone.

The Sun Ray is a thin-client terminal made by Sun. It has the ability to connect to UNIX, Linux, and Windows servers through various terminal systems, including X and Windows Terminal Services. The Sun Ray has a slot for an access card; plugging the card into the unit tell it which server to connect to, and automatically logs you into your phone as well. With the “Hot Desk” system, you do not need to log out of the system at all, you just pull the card and walk away. When you put the card into another phone, your session starts up quite quickly (under 5 seconds in my testing) and everything is exactly as you left it. Even better, your phone settings follow you. I was given two access cards, one for a user with a Windows account, and one for a Linux user. The only trouble I had with the cards was the time I put it in backwards, the Sun Ray 2 unit did not seem to notice that a card was put in incorrectly.

The Sun Ray 2 itself worked great. I tested this device from my home office. I spend a lot of time using Real VNC and Remote Desktop from my home office, and the Sun Ray 2 blew them away. Period. Mitel set me up with a Windows account and a Linux account (X term to a Cent OS server). The Windows machine ran at my full monitor resolution (1650 x 1050) at 16 bit color, and felt as responsive as a directly connected computer. What makes this even more amazing is that my connection is a cable modem connection, and their offices are located in Canada while my office is in South Carolina. That distance usually introduces enough latency so that you can “feel” it, but I did not notice it at all. Outside of that, the experience of using the Sun Ray 2 is strictly up to how the server on the other end is set up, so your mileage will vary.

It sounds good so far, the but phrase “thin client computing” always seems to raise string emotions. My experience has been that in some environments, for some workers, thin clients of this nature make perfect sense. I spent much of my time working in a call center, for example; in that call center, I really wished we had thin clients and not desktop PCs. Handling a shift change in a call center either involves a 15 Ð 30 minute period of having reduced staffing levels as some users close their day out and others get ready, using the same PCs, or it requires having twice as many PCs as the largest shift has employees and paying people overtime to come in early to set up. Either way, it is a lot of money. A great many workers do not do anything particularly resource intensive, yet the IT department has put an 80 watt space heater on their desk (which in turn needs the air conditioning to be working hard), just to use Word, Outlook, and Internet Explorer. The Sun Ray 2 unit uses under 10 watts of power, which can provide a significant cost savings on the client side, and server rooms are much easier to make energy efficient than desktop environments. And of course, a thin client scenario centralizes and consolidates storage/backups, allows the It department to “lock down” the system, eliminates concerns of removable storage, and so on. Thin clients are not for everyone, but they can be the right solution in some scenarios.

Unfortunately, I was not able to evaluate the server-side half of this equation, or the setting up of the access cards. But I can say that I am impressed with the performance of the device on my end. If you are in an environment with existing thin client users, or are looking to transition users to thin clients, the Mitel Unified IP client for Sun Ray packages are definitely worth your time to look at.

WARNING – Optiquest Q241WB 24″ LCD is not an 8-bit panel.

June 21st, 2008 13 comments

I bought an Optiquest Q241WB 24″ LCD display after seeing how brilliant the display looked in the store at Fry’s Electronics.  It was obviously the only 8-bit per color LCD panel on display in the computer monitor section and it looked awesome and it was on sale for a mere $350 with a $50 rebate.  I picked one up even though it was an open-box model since there were no notes warning about dead pixels and I could always return it if I didn’t like it.

Well as it turns out, there were no dead pixels but all the pixels could have been dead as far as I was concerned.  To my surprise, the display was NOT the same panel technology being displayed on the show floor at Fry’s.  This was not the brilliant 8-bit PVA LCD panel being shown but it was a typical ugly 6-bit TN LCD panel yet it came with the same model number.  This is a very deceptive practice because it fools reviewers in to giving the display glowing reviews and shoppers get fooled by the beauty of the display in the store.  Viewsonic needs to STOP this behavior immediately and Fry’s (or any other store) need to warn their customers what what they’re showing is not what’s in the box.  A lot of consumers who wouldn’t know any better might have kept the display.  This is clearly a case of bait and switch and it’s false advertising.

More problems with NVIDIA chipset motherboard

June 19th, 2008 4 comments

The NVIDIA 7150 integrated graphics motherboard and chipset is giving me more problems.  This is the XFX nForce 630i model MG-630i-7159 motherboard I’m testing which has a lot of potential when I overclocked an Intel Allendale to 2.93 GHz effortlessly.

I really want to love this motherboard and chipset for all its potential at an affordable price, but I still can’t get S3 sleep state working and the system locks up after I wake it up and log in.  I still can’t get a good answer from NVIDIA nor have I heard from XFX regarding the problem.  I don’t know if it’s the motherboard implementation or NVIDIA drivers.

Now I’m having problems with the NVIDIA desktop resize utility which is impossible to use on a DLP screen that overscans the edges.  For some reason I can’t see all the controls on the resize screen and the continue button is probably off the edge of the screen.  Even when I manage to change the settings, it snaps back to the default setting as soon as I click apply in the NVIDIA control panel.  I resized the screen to a slightly lower resolution that’s about a little more than 1700×900 pixels and that makes it slightly more usable but it’s less than ideal.

This is also a good reason to really dislike rear projection screens because they chop the edges off.  My particular model is also interlaced even though it claims to be a “1080p” display.

Book Review: ISA Server 2006 Unleased

June 18th, 2008 3 comments

For the last few months, I have been working with ISA Server 2006 in our corporate network. Before I got started, I purchased a copy of ISA Server 2006 Unleashed by Michael Noel, published by SAMS Publishing. I was hoping that this book would be a valuable asset in working with ISA Server, particularly since Tom Shinder has not updated his ISA Server 2004 book. This book missed the mark, and badly.

For me, I have a persistent problem with IT industry books. I have this ability, as many people have, to read the directions on the screen. Furthermore, I understand enough of the principles of whatever I am doing to not need a basic primer on every minor detail. Put simply, if I don’t understand what I see on the screen, I can look it up. So my needs from a book are to tell me things that I are not on the screen.

This particular book, like many other IT books, is rarely more than a screen-by-screen walk through of ISA Server. And that is disappointing to me. I don’t need a book telling me, “on this screen, enter the directory that you wish the application to be installed to.” Thanks, but I figured that out when it said, “where do you want the application to be installed?” What I need is a book that contains answers to my questions. Instead of saying, “these are your three choices” I need to know the pros and cons of the choices. When something goes wrong, or not as expected, I need to be able to turn to the book and get an authoritative answer instead of having to spend hours on search engines. And this book simply does not meet my needs.

If you are looking for an introduction to ISA Server 2006, or want to explore its feature set without having to install it, this is a good resource for you. But if you are actually working with ISA Server 2006, and need something more in-depth, you’ll want to pass. A much better title for this book would have been ISA Server 2006 Walkthrough.

Do we really want “wetworks”?

June 18th, 2008 7 comments

I love to read stuff from Microsoft Research. Say what you willa bout their shipping products, their research items are just plain fascinating, and I have learned a lot by reading their papers. I came across an item today, an interview with a guy there working on human/computer interfaces, Desney Tan. It was interesting; he talked about “wetworks” (merging the brain and the machine) fairly casually.

Now, I am all for technological progress, I am certainly no Luddite. But the idea of wetworks somehow bothers me in a weird way. Not really moral qualms, per se. But practical issues. Things like, “if my brain is wired up like this, what happens if I ever need an MRI?” And, “if my brain is tightly coupled to a machine, what happens when the machine crashes?” Another one: “if I am tethered to a machine, what powers it? What happens if it runs out of power?” And so on.

It’s odd, I’ve read a lot about people working on the “tough problem” which is the machine/brain interface. But no one seems to really be addressing the practical problems. I think that until these practical issues are dealt with, this will not be a serious technology except in niche markets.

I am a new Senior Analyst at Washington DC based Think Tank ITIF.org

June 17th, 2008 18 comments

It’s been nearly 3 months since I departed ZDNet.  I’d like to thank everyone who has helped me after getting laid off at ZDNet.com regardless of whether it led to anything or not.  I’m not mentioning any names but you know who you are and I want you to know how much I appreciate your help.  It’s been a rough two and a half months and my friends and colleagues have made all the difference in the world.

This week, I’m proud to announce that I’ve officially joined Washington DC based Think Tank ITIF.org (The Information Technology & Innovation Foundation) as a Senior Analyst.  I will still be based out of Silicon Valley working remotely and I’ll occasionally fly to Washington DC, Brussels, and anywhere else I need to be.

Just two years three months ago I worked as an IT consultant.  These last two years I’ve been a blogger and journalist covering IT and technology.  Now I’m starting a new chapter in my career and I look forward to it.

Some have asked me in the comment section below if I intend to keep blogging here.  The answer is yes, I will continue to blog here.

Innovation 08 panel on Net Neutrality at Santa Clara University

June 14th, 2008 64 comments

Thursday morning I sat on a panel at the Innovation 08 Net Neutrality event at Santa Clara University.  This came right at the heals of my Brussels trip where I gave a presentation on Net Neutrality to the some members of European Parliament and various industry folks.  The jet lag wasn’t so bad but the bigger problem for me was missing my 6 year old daughter’s first big singing solo at her school which had to be at the same time as my panel.  I spent a lot of time training her so it was certainly a big disappointment for me.  The jet lag certainly did have a lot to do with why this blog wasn’t posted earlier yesterday.


Richard Whitt, George Ou, Ron Yokubaitis, Richard Bennett, Jay Monahan

The story didn’t get too much coverage (yet) but here we have some coverage from Cade Metz.  I guess it’s a slight improvement because Metz at least didn’t try to falsely insinuate that I was against transparency for Comcast this time.  It was gushing with love for Google but at least he quoted me accurately and got my point across.

Ou is adamant that – whether it (Net Neutrality rules) forbids ISPs from prioritizing apps and services or it forbids them from selling prioritization – neutrality regulation would actually prevent things like video and voice from flourishing on our worldwide IP network. “If you forbid prioritization, you forbid converged networks,” he said. “And if you forbid converged networks, you get a bunch of tiny networks that are designed to do very specific things. Why not merge them into one fat pipe and let the consumer pick and choose what they want to run?

This is such an important point because latency/jitter is a killer for real-time applications like VoIP, gaming, and IPTV.  As I showed in my research, even mild usage of BitTorrent on a single computer in a home can ruin the experience for everyone in that home.  If prioritization technology is banned in Broadband, then we’ll simply end up with less functional broadband and we’ll have a statically separated IPTV service.  With a converged IP broadband network that delivers IPTV and Internet access, the consumer gets a massive converged pipe and they have the power of control at their fingers when they turn off the IPTV to free up all that bandwidth for their Internet service.  If the Government prohibits intelligent networks that guarantee quality of service, ISPs will be forced to separate their TV and Internet pipe with a fixed boundary and the consumer gets left with a permanent slow lane rather than getting a slow lane plus a fast lane that they can dynamically allocate to their TV or their Internet.

Metz also couldn’t resist from taking a personal jab at me and Richard Bennett:

“The panel also included George Ou and Richard Bennett, two networking-obsessed pals who have vehemently defended Comcast’s right to throttle peer-to-peer traffic, and Whitt received more than a few harsh words from Ou.”

The disparaging tone was uncalled for and when you put it side by side with the treatment he gave to Google, the bias is blatantly obvious and journalistically unprofessional.

Metz swooned for Google’s

“The question was raised by the top level management at Google: What do we think about network neutrality Ð about this notion that broadband companies have the power to pick winners and losers on the internet?” Whitt explained. “One position was that in the environment [proposed by Whitacre], Google would do quite well.”This side of the argument said: We were pretty well known on the internet. We were pretty popular. We had some funds available. We could essentially buy prioritization that would ensure we would be the search engine used by everybody. We would come out fine Ð a non-neutral world would be a good world for us.”

But then that Google idealism kicked in.

Idealism huh?  Too bad Metz left out the part where Google’s Whitt admitted that they were against network intelligence and enhanced QoS even though he refused to answer a simple yes/no question on whether he and Google support the actual Net Neutrality legislation.  Make no mistake, Google’s position is based on crippling their video competitors in the IPTV market which is critical to adding competition in the Cable and Satellite TV market which is far more expensive and relevant to every-day Americans.  It has nothing to do with Google idealism.

Ron Yokubaitis went off with the typical spiel about how DPI (Deep Packet Inspection) was all about violating user privacy, reading consumer’s email to inject ads, a tool of the big bad RIAA/MPAA for figuring out what song or movie you’re downloading, and how this was similar to communist China.  Yet DPI has nothing to do with reading email since that is a function of spam filters and it has nothing to do with violating people’s privacy.  DPI is merely a mechanism that analyzes which protocol someone is using and it really isn’t a method used by the MPAA and RIAA.

I also pointed out that it’s ironic that it is companies like Google who wants to inject ads and data mine your Gmail account and it was ironic that we bash the telecoms when it’s companies like Google that censors information from the Chinese people.  I’m also reminded that people were imprisoned in China for simply speaking out because of search engine providers like Yahoo turning them in to the Government.  Perhaps this wasn’t a great tangent for me to go off on but I get irritated by the wrongly focused attacks on ISPs when it’s often more appropriate for search engine companies.

Richard Bennett also posted something about this event and wrote

What really happened is this: Google has invested hundreds of millions of dollars in server farms to put its content, chiefly YouTube, in an Internet fast lane, and it fought for the first incarnation in order to protect its high-priority access to your ISP. Now that we’re in a second phase that’s all about empowering P2P, Google has been much less vocal, because it can only lose in this fight. Good P2P takes Google out of the video game, as there’s no way for them to insert adds in P2P streams. So this is why they want P2P to suck. The new tools will simply try to convince consumers to stick with Google and leave that raunchy old P2P to the pirates.

I’m not so sure if Google really feels threatened by P2P since P2P cannot deliver a good on-demand streaming experience beyond 300 Kbps or whatever the common broadband upstream speed is. That’s the problem with out-of-order delivery from a bunch of peers that may or may not be there unless it had several times more seeders than downloaders. Since the normal ratio is several times more downloaders than seeders, you simply can’t do high-bandwidth in-order delivery of video. This is why you’re not seeing YouTube take a dive in popularity and every instant-play site uses the client-server CDN delivery model.

The main reason P2P is so popular is because there is so much “free” (read pirated) content available. The actual usability and quality sucks compared to commercial video on demand services. Not only do you get lower quality and lower bitrates in the 1 to 1.5 Mbps range, you have to wait hours for the video to finish before you can start watching it and it even hogs your upstream bandwidth in the process. Legal for-pay services such as Netflix all use the client-server CDN (Content Distribution Network, caching technology) delivery model because it offers an instant play experience and the video quality is much higher quality at 4 Mbps. Other services like Microsoft’s Xbox Live Market Places use client-server CDN to deliver roughly 6.9 Mbps.

While it may be possible to get 6.9 Mbps from a P2P client, it’s rare that a single Torrent will be healthy enough to hit that speed and it certainly won’t arrive in order making it impossible to view while you download.

Problems with Lingo VoIP phone service

June 14th, 2008 5 comments

Last Sunday I had a hell of a time getting my Lingo VoIP phone service to work properly.  Certain phone numbers I was calling wouldn’t transmit audio while I could hear sounds coming in.  I had this problem before and it went away after I toggled the codec settings from G.729 to G.711 and rebooted the ATA (Analog Telephony Adapter) that came from Lingo which doesn’t exactly inspire confidence in the stability of the “solution”.  This time no amount of toggling or reboots of the ATA or my home router which sits in front of the ATA would work.

So I call Lingo tech support and got through in a short amount of time to a human on the other line.  After talking a little bit, the tech tells me that I have to set the ATA behind a “DMZ” port behind my home router which makes the ports a little less restrictive.  But in order to do this, I had to plug a laptop in to the LAN port of the ATA and connect to 192.168.0.1 to configure the WAN port of the ATA to be a static IP address of something I use on my LAN behind my router.  Only then would I be able to set that static IP as the DMZ address on my home router.  For someone like me this is more of a hassle since I do understand this stuff but if that last few sentences confuse the hell out of you, I can’t blame you.

So after I do all this, it STILL doesn’t work.  The tech then tells me to shut down the ATA while he reconfigures the ATA settings to use phone port 2.  So I reattach my phone to port 2 and then boot up the ATA after waiting for a minute and the system STILL doesn’t work and my mom still can’t hear a word I say when I call her.  Other phone numbers worked by the local area codes and the area codes nearby refused to work.  But after a few minutes, the service mysteriously started working again.  So much like the codec toggling trick, this “solution” makes no sense and I have no idea how permanent or reliable the “fix” is.

If that wasn’t enough, the Lingo service promises free calling to Europe.  But when my wife tried to call me while I was in Brussels, the first dozen or so attempts failed.  When it finally got through to me, the sound quality sounded absolutely awful compared to the toll call I made to her.

Lastly, I have to consider all the outages I’ve had with the crazy power outages I’ve had here in Silicon Valley and the housing complex I’m at plus the 2-day DSL outage I had and it’s been frustrating not using traditional powered analog phone service.

So does this mean I’m giving up Lingo?  Not yet, the price of $22/month for flat rate calling to the Americas and Europe along with the portability of the ATA box still makes it compelling.  But the lack of reliability, complexity, problems, and some quality issues certainly puts a damper on my enthusiasm for the service.

More Vista-isms in Windows Server 2008

June 13th, 2008 3 comments

I keep finding more and more places in Windows Server 2008 where I get the distinct impression that someone desparately needs to do s/Vista/Windows Server 2008/ on it (regex for “replace ‘Vista’ with ‘Windows Server 2008′”). Everywhere I look, some part of the system is referring to itself as “Vista”. These are not items being driven by the Windows version number, this is documentation and so on. It’s just plain sloppy, and shame on Microsoft for releasing it in this condition.
