Linksys SPA3000 Analog Telephone Adapter 1 Port FXO + 1 Port FXS Review

Linksys SPA3000 Analog Telephone Adapter 1 Port FXO + 1 Port FXS
Average Reviews:

(More customer reviews)
This is a powerful product, but with lots of settings, no manual, and some complexity to configure.Once configured, it works beautifully.I've configured it so that our local calls go out through our regular local phone company on the regular local phone line, but our long distance calls seamlessly go out via SIP on our VOIP provider.My non-technical wife just picks up the phone and dials any number, and it automatically figures out how to place the call for a good rate.Incoming calls just come in seamlessly.Caller ID works fine.It took about five evenings to get it set up properly, and I have a degree in computer science and lots of computer networking experience.

There's no manual provided with the product, and Sipura has not made the manuals easily visible on their website.If you're thinking about this product, do a web search for help in figuring out how to configure it.This is NOT something you'll just figure out without documentation.

Some embedded documentation would help this product tremendously. It's mostly configured via a web browser; while configuring, I should be able to click a "help" button for an explanation of what the various fields do.Even a well-written paper manual would help (the .pdf file I found wasn't so great).If this product were documented properly, it'd almost certainly rate 5 stars.

The SPA-3000 continues to deliver on Sipura Technology's mission to provide market leading, best-in-class VoIP end points providing freedom and opportunity to service providers and end users.The SPA-3000 features VoIP adapter functionality found in the SPA-2000 and SPA-1000/1 with the additional benefit of an integral connection for legacy telephone network "hop-on, hop-off" applications. SPA-3000 users will be able to leverage their broadband phone service connections more than ever by automatically routing local calls from cell phones and land lines to a VoIP service provider and vice versa.A typical user calling from a land line or mobile phone will be able to reduce and even eliminate international and long distance telephone charges by first calling their SPA-3000 via a local phone number or by using a telephone connected directly to the unit. The advanced authentication and call routing intelligence programmed into the SPA-3000 will connect the caller via the Internet to the far end destination with security and ease. Using the SPA-3000 at the far end, calls can be answered immediately or further processed as a local call to any legacy landline or mobile phone allowed by the SPA-3000 dial plan.

Cisco SPA2102 VoIP Phone Adapter with Router Review

Cisco SPA2102 VoIP Phone Adapter with Router
Average Reviews:

(More customer reviews)
This adapter is excellent for those tech-savvy enough to configure.

Echo cancellation and jitter buffer work well.

The latest firmware allows you to increase the DTMF detection timing so that talkoff (spurious DTMF) can pretty much be eliminated. Currently, this can't be done using a PAP2T-NA adapter. This setting is under "Admin -> Voice -> Advanced -> Line1/Line2 -> DTMF Tx Strict Hold Off Time".

If your VOIP provider supports it, then T38 faxing works fairly well, with adjustable redundancy levels.

I've tried many other adapters and always had trouble, this is the only one I'll buy from now on. Anyone interested in a used PAP2T? :)

Cisco PAP2T Internet Phone Adapter with 2 Ports for Voice-over-IP Review

Cisco PAP2T Internet Phone Adapter with 2 Ports for Voice-over-IP
Average Reviews:

(More customer reviews)
You need to know what you're doing to really get the most out of this device, but really, this device works fine. I own several of them and use them for my business and home.

To get it to work, you need to sign up for a SIP account with a VOIP provider, like Voip.ms, Voicepulse, Vitelity, or Callcentric.

I suggest updating the firmware as soon as you receive it, as there are frequent useful firmware updates.To respond to some of the one star reviews:

Of course the device doesn't work with Vonage, it's not supposed to! Vonage doesn't use SIP!

Of course the device died when you plugged the wrong power adapter into it - it fried the circuit board. You could make that same comment about hundreds of devices.

UPDATE: While I still think this device is good, I now recommend purchasing a Linksys SPA-2102 instead, due to a new firmware update from Linksys. It's worth the extra $[...] or $[...] bucks for the ability to tweak DTMF detection.

Siemens Gigaset Digital Cordless Phone with Hybrid IP/Landline Calling (A580IP) Review

Siemens Gigaset Digital Cordless Phone with Hybrid IP/Landline Calling
Average Reviews:

(More customer reviews)
I am reasonably technical and run a VOIP PBX for our small business with several different providers, IP Phones and gateways.This seemed like a nice addition where cordless IP phones are needed.I have almost returned this several times because of the UI and contact import issues, however I am keeping it in hope of an updated firmware release.

Pros -
Good voice quality
Register multiple VOIP Providers
Price is right for an expandable VOIP based ATA and handset

Cons -
Handset Interface and Features are a mess to use - Siemens could learn something from other cordless handset manufactures
Vcard contact import is a nightmare
Can't seem to remove internal Gigaset setting/provider
Web interface is acceptable If you do the upgrade... if not it is so slow you can' use it.
No Headset Jack (are you kidding me?)

I want to like it... but not quite prime time.

Cisco SPA942 4-Line IP Phone with 2-Port Switch Review

Cisco SPA942 4-Line IP Phone with 2-Port Switch
Average Reviews:

(More customer reviews)
We purchased a half-dozen of these for my startup because they're supported by Vocalocity (our VOIP provider), had the features we want, and the price was right. It's a solid, few-frills, get-the-job-done VOIP phone. Excellent sound quality, and it's attractive on the desk, too.

My only complaint is that the phone uses icons (a picture of a hand for "hold", a piece of paper with a folded corner for "setup") instead of words. At first blush, it's not always intuitive what those icons mean. I understand why Cisco did this (reduced localization costs for a product that can sell in the global market). I almost never read the documentation that comes with electronics, so the first time I needed to place a call on hold, I spent 60 seconds staring at it looking for the "hold" button, dumbfounded that it didn't have one.

Cisco SPA941 4-line IP Phone with 1-port Ethernet Review

Cisco SPA941 4-line IP Phone with 1-port Ethernet
Average Reviews:

(More customer reviews)
I put together two Asterisk servers for two businesses, and bought several of the SPA941 phones.I looked at Grandstream products, and read reviews, and bought one, but they are basically cheap crud in comparison.This SPA941 series is a solid business phone that works well... the cheaper competitors feel like cheap plastic (they are), and have all kinds of operational issues working with Asterisk.I'm basically a fan of this product.

On the down side, I have had trouble getting and installing the 2-to-4 line upgrade.Be aware that this is only a 2-line phone, even though it has 4-line buttons.
