Linksys SPA2100 ATA Review

Linksys SPA2100 ATA like to be good job.I did a lot of research on which one to buy and decided on a Linksys/Sipura model as they seemed to be reliable and the majority of people had positive things to say about them. I chose the Linksys SPA2100 for two reasons: A) because it had a WAN and a LAN port, which meant simply putting it between my DSL router and my PC, and B) because it had two FXS (phone) ports, so I could set one up with a permanent service (I use Callcentric, who have been very helpful in my learning phase) and then use the second one to play with, changing settings and providers to my hearts content while knowing I could still make and receive calls on the first port (as it turned out, the novelty of that wore off and I always keep Voipuser on the second one).

The Feature Set Clinched It

One other thing that the Linksys SPA2100 had in its favour was the QoS bit – it can tell the router it wants a higher priority than less important stuff, such as email, so the speech quality is not affected unnecessarily. I would have thought that this would have been a primary requirement for any ATA, however there are a lot of them (including some SPAs) that do not have QoS.

When my Linksys SPA2100 first arrived, I was pleased to see it even included a cable to connect to the DSL router, so it was ready to plug in and play with, which I did.

In Use

I managed to get the thing working adequately with Callcentric in a very short time, however it took weeks to get it to function properly with Voipuser (one way speech, then calls to the 0844 number telling me I was unavailable, despite the web site telling me I was logged in).

My problems were partly caused by the Linksys SPA2100 being so configurable that I didn’t know what I was doing, and partly because I am a male and therefore played around and didn’t bother reading instructions. Fortunately for me, someone else must have previously experienced the same issues and they shared their findings (I still haven’t read the Linksys SPA2100’s manual, although I did get as far as downloading it in a moment of despair).

Now that I have a fully functioning Linksys SPA2100 I am thrilled with it. The speech quality, whilst not being as good as PSTN calls, exceeded my expectations. The codec used obviously makes a great deal of difference to speech quality, although more often than not it uses the G711u codec, despite me telling it that G729a is my preferred one (G711u has got to be the best quality one it has, but I hate to think how much bandwidth it eats).

The echo cancellation seems to be as good as the ones the used in the PSTN international gateways here, and the only time I have experienced echo was when the far end user tried to put me on speakerphone (which I hate anyway).

Advanced Features

Having got the speech basics working, I set about making the Linksys SPA2100 do other things I consider important, namely making itself appear to fit in with my telecommunications ideals. To this end, I taught it how to make proper tones (it defaults to US tones – ewwww) and proper ringing cadences. This is where the ultra configurability that initially caused me problems now became my friend – my SPA now goes “ring ring” when someone calls me. It was worth teaching it the tones too, because although Voipuser seems to pass the ringing tones from the B party back to me (I like that), Callcentric does not; the ringing tone I get when making a Callcentric call actually comes from the Linksys SPA2100 (this is not the SPA's fault) and the speech path is only established once the B party answers (giving a short delay between losing ringing tone and being connected to the callee).

Other PSTN-like things the Linksys SPA2100 can do include CPC (sometimes called Clear Forwarding) and Answer Reversal, which means it can interface with analogue PABXs and answerphones and work as you would expect. The dialing plan is user configurable and can do useful things such as number translation, which is handy if you don’t want to keep dialing **275*448 in front of a Voipuser number when calling from other VSPs.

I like my Linksys SPA2100 so much that not only would I recommend it to people, but I also bought a second one as a gift for my father. Having learnt the hard way, I first configured it via the link I mentioned above, then entered my own account details into it (hey, I had to make sure it was working before I gave it away!), made test VoIP calls (in and out), made PSTN calls in and out, and it worked. Completely set up in less than an hour, including changing the tones and ringing.

The Linksys SPA2100 was also very cost effective at $NZ138 (approx £46).

Conclusion

I have worked in the telecommunications field for over two decades (including a few years in international) and I have high expectations from a phone. The Linksys SPA2100 gave me more features than I expected at a higher quality than I expected. There is nothing that I feel is missing from it, although some people might like an FXO (central office) port, but then those people would not have bought this model. I specifically did not want an FXO port as I like to consciously choose whether to make a VoIP call or a PSTN call – I don’t want to make a call assuming it’s free only to find out it’s been routed via the PSTN at exorbitant rates. Also, I have it running through a small PABX, so the only difference to me is which access code I dial (one for each of my PSTN line, SPA port 1, and SPA port2).

Linksys SPA-921 Review

Linksys SPA-921 is cheapest model from Linksys after the Linksys SPA-90.
How good about Linksys SPA-921.

Introduction

The Linksys SPA-921 built by Sipura/Linksys is the second cheapest model from Linksys after the Linksys SPA-901, which doesn't have an LCD screen. The SPA-921 currently sells for $110 at www.telephonyware.com from which I bought it.


Installation


Hardware-wise Linksys SPA-921 , it's pretty simple: Just plug the network cable into a switch/hub connected to the Net, and plug the 5V transformer.


Software-wise, it's as rich/complicated as the 3102 VoIP gateway, which means multiple web pages that only make sense if you're already used to VoIP (and even then.) Hit the Admin Guide PDF for more information.


Basically, you need to create a new VoIP account, enter login/password and the server IP address, add a STUN server if you're behind a NAT router, and you should get a dialtone.


Usage


Like other phones, I think it has too many buttons, but it's simple enough for basic usage.


Besides a few buttons that are set to only one feature (Voicemail, Menu, Hold, Mute, Headset, Speakerphone, Volume), it relies on four buttons under the LCD screen along with a four-directional round button to navigate through menus. As an alternative, you can configure the phone through its embedded web interface.


Conclusion


It's a nice, affordable, entry-level phone.


There are just a couple of things I don't like:

- Contrary to what the documentation says (at least, as of May 2007), it cannot download a phonebook from a server
- Like the Linksys SPA-921, the phonebook only holds 100 entries
- The LCD screen cannot be raised, hence the need for the desk stand that comes with the unit. The GrandStream GXP-2000 is better in this respect
- The screen is a bit small. The GXP-2000 is also better for this
- Unlike the SPA9x2 phones, the interface is only available in English

Second look and invites for AT and T's improved Pogo web browser

AT&T both intrigued and confused us back in April when it announced Pogo, a new Mozilla-based web browser (of all things) that they're testing in a very private beta. It's notable for some new ideas about how web browsers should present information, and we found some of them interesting when we gave Pogo a thorough testing. But the remarkably heavy system requirements needed to come down out of the clouds for Pogo to attract much of an audience. Today, AT&T told us that a new private beta is ready to roll, and the system requirements have been significantly reduced—the company gave us 500 invites to share with Ars Technica readers so you could see for yourself.

Not much has changed about Pogo's UI or functionality since we first reviewed it, so we aren't going to rehash much of our previous coverage. In a nutshell, Pogo is AT&T's first step into an increasingly competitive web browsing market, one that's heavy on visual flourishes. Really heavy. Pogo uses baroque 3D scrolling visualizations to present categories of thumbnailed bookmarks and your browsing history, as well as a Dock to present open pages in thumbnailed "cells" (tabs, in normal speak). There's even an Opera-esque Springboard that presents a grid of your favorite sites for easy access.

Back in April, though, Pogo's heavy emphasis on a visual UI (one that sometimes eschews usability) came with a price in terms of performance that was surprisingly high. The minimum system requirements included a 1.6GHz processor, 2GB of RAM, and a video card with at least 256MB of VRAM. This obviously meant that we couldn't take Pogo for a spin in any Windows virtualization apps, but it turned out that some respectable PCs with very capable video cards couldn't even handle it. When we brought out the big hardware guns, Pogo still brought the machine to its knees with barely three tabs cells open. At that point, it was clear why Pogo was available only in a very private beta.

Now Pogo is back with some significant performance enhancements and system requirements that have been cut virtually in half. While there aren't any whiz-bang new features, Pogo can now run with a 1.0GHz processor, 1.0GB of RAM, and a video card with 128MB of VRAM. Since Pogo was arguably doing fine in the whiz-bang department already, we figured it was worth another spin.

This time around, we installed Pogo beta 1.1 on a Vista Home Premium install running native on a quad-core 2.6GHz Mac Pro with 3GB of RAM and a GeForce 7300 GT video card sporting 256MB of VRAM. We hit the ground running by opting to have Pogo import our del.icio.us bookmarks—all 1,680 of them—which took well over 10 minutes. Initially we assumed that Pogo was preemptively caching a thumbnail for every bookmark it imported as it went. Unfortunately, we were asked to create said cache after the import process' "all done!" ding woke us up.

Pogo's attempt to render lists of bookmarks as old 'n busted
Again, we won't rehash all the different visuals that Pogo brings to things like bookmarks and browsing history. While our test machine this time around is actually a bit lighter-weight than the Opteron 256 with two 3GHz CPUs (as well as 4GB of RAM, and an NVIDIA 8800 GT video card with 512MB of VRAM) that we maxed out our testing on last time, we're happy to report that Pogo's performance has improved quite a bit. While just three open pages rendered Pogo useless back in April, Pogo remained acceptably responsive with as many as 6-10 pages open.

That said, our Quad Mac Pro test machine is still well above Pogo's new minimum system requirements, which makes us wonder just how well such a UI-intensive browser will perform on most people's computers, which are probably closer to Pogo's minimum system requirements than to the "recommended" stats.

On a more general level, after our second time around the block with Pogo, we wound up questioning how useful the visually rich UI actually is. Playing with Pogo again and putting its notable features through the ringer left us wondering if Pogo's developers watched Minority Report one too many times.

But don't take our word for it—the Pogo team wants to give Ars Technica readers 500 invites so you can take it for a spin yourselves. Just head over to the Pogo site and enter "r3STRPgV" as your invite code, but make sure your machine meets the default system requirements (we know: it feels weird having to warn you guys about system requirements). If you fire Pogo up though, definitely let us know what you think about it and the specs of the machine you're running it on.

Tokyo Telco Bets Big on VoIP

telecom services venture Japan Communications is expected to lease wireless spectrum from NTT DoCoMo (DCM) for a new type of cell-phone service. The Tokyo company is likely to be the first operator in Japan to offer mobile handsets that can make calls on-the-go using voice-over-Internet protocol technology.

JCI's service and other mobile VoIP services like it have the potential to change drastically the economics of cellular services. Analysts say that VoIP should mean lower rates for subscribers, especially for long-distance calls. That's good news for users in Japan, where basic monthly rates average around $60 and are among the highest in the world.

JCI officials have a loftier goal: Simplify communications by routing mobile-phone calls through the same digital channels we now use to browse the Net. Microsoft (MSFT) and Cisco (CSCO) have been pushing this concept, known as "unified communications," in recent years, but hurdles remain even for these tech giants.

VoIP providers to get full 911 access with bill's passage

VoIP has had its ups and downs when it comes to accessing 911 emergency services, and some incumbent telcos haven't made things easier for VoIP providers like Vonage. Finally, the US Senate has passed legislation that requires 911 network operators to allow VoIP customers to get through, no matter what service they're calling from.

After a woman blamed Vonage for not connecting her to 911 and the resulting death of her baby in 2005, the FCC gave VoIP providers a 120-day ultimatum to implement 911 service. At first the companies had trouble meeting the deadline, but today VoIP providers boast that more than 97 percent of their customers have E911 (Enhanced 911) service. In February this year, the Senate passed legislation that requires all VoIP providers to supply their customers with E911 service, which properly transmits a callback number and address to 911 dispatch centers.

Despite this legislation and the VoIP industry's reports of E911 access for nearly all customers, we still see claims from VoIP providers that the incumbent telcos who operate the proprietary 911 system have been deliberately blocking VoIP access in order to stifle competition.

Those days may soon be over with the Senate's passage of the New and Emerging Technologies 911 Improvement Act. With the House having passed the legislation as well, it's now expected to be signed into law.

In addition to leveling the 911 access, the legislation gives dispatch centers liability protection when handling VoIP calls. An amendment added by Sen. Ted Stevens (R-AK), the bill will also require the US government to develop next-generation 911 capabilities and extend the range of these networks to the rural areas that are not yet endowed with E911.
