While I can't be 100% sure that the Bonjour issue was the only setting affecting implementing the device, it is working well with Bonjour not running on the ATA, and I can use a soft phone app on my MacBook to place and receive calls

these worked great to setup analog fax machines with vonage

Our fax machine is analog so this product coverts the fax line coming as digital to analog so our fax machine will work.it is working great so far.

Well, finally, this ATA has been working fine for a while now, with Caller ID and no problem with incoming calls.

YesIt works just fine with no issues with the alarm system and an old style answering machine

BTW, I also sell VOIP service for business and resident at excellent competitive price; therefore, if you need phone service feel free to contact me.

All in all, the price is right, give it a try, but don't be broken hearted

Used this to install an inexpensive 911 voice dialing setup that utilizes VOIP , Amazon echo dots and an echo connect

I would not purchase the next higher model with a built in router if all you want is a reliable voice connection

The bad news, I wasn't able to find something that supports Google Voice

Excellent Product, clear voice transfere, very realable system firmware

The device is somewhat OK if you only plan on using it for voice usage, however it has quite a number of issues:- Faxing is very flaky, even with T.38 enabled and a T.38 compatible SIP provider

For the most part, this SIP adapter works great.

(there are some bugs in the provisioning code, for example, which I am not using, so it doesn't matter to me)UPDATE 2 years later: as far as I know, this is the best SIP box available on the market.

After going through the setup process, which I recommend only for professional/experienced users, I found that the SPA112 did not work as expected

This replaced my dead PAP2T and was super easy to set up with VOIP.ms.http://wiki.voip.ms/article/Devices#Cisco_SPA112_and_SPA122

Setup however was not fun and unless your registered with Sysco and certified they will not share the documentation necessary for configuration

Setup is super easy as most places provide documentation for this device because it is so popular.

Setup was easy, call quality was good, and lag (ring delay) was low

Works well, configuration is not as straight forward as I expected

Easy configuration, working flawlessly with Callcentric.

installation was easy, configuration was pretty easy, I was able to replace an existing high cost land line.

Did not work as we needed

this was recommended by the Vonage customer service rep, works just as expect, after configuration of the adapter

their tech support is good, they remoted onto my machine and set it up when i purchased the service.

The tech support at my provider was unaware of this detail and have added it to their internal knowledge base.

Used tech support for my provider as well as my VOIP provider.

Using this with sipgate, works flawlessly, never had an issue!, 3 months continuouse use so far, it's like having a uk phone in the us!

The end result is a reliable home phone that costs me under $3 dollars per month

This will *not* support VOIP phones and wasn't designed as such.

I bought this and set it up with Callcentric's service, to replace my overpriced cable company phone line

Also, I had fun using some older phones we had lying around on our modern network; something about having an early '80s phone working on a modern VOIP network just made me happy

I created an account on the voip.ms site, followed their instructions for configuring the SPA112 to work on their system, and it worked the first time.

and it still stops working randomly couple times a month - phones are

(I had a hard time finding something comparable)

I followed the configuration instructions supplied by my service provider (Callcentric) for this particular model, and the adapter immediately connected went to work as soon as those were completed

Bought several of these and they were very easy to set up and have been perfectly reliable and deliver excellent call quality

It seems to perform as advertised, I have no problems or complaints as of yet.

I had heard that the SPA112 had great call voice quality and Amazon was not selling the OBi200 at the time

Did not work as we needed

CISCO provided excellent instructions in the package which proved to be 100% accurate

Configuration easy as long as your carrier gives good instructions.

works great but need better instructions and how to online was difficult also, but I called customer service and they were very

The user interface is easy and my provider (callcentric) had nice clear instructions on their website so it was not difficult.

Summary: apparently untested firmware bricked the device

I bought this to replace a failed ATA device and know a little about what I am doing, so I figured this would be easy

A large VOIP company, having a back order, or otherwise unavailable faxbridge device

This device has a good reputation and is performing exactly as I expected

I spent alot of time hunting down vendors that are capable of using this device, I found a few.

It seems to perform as advertised, I have no problems or complaints as of yet.

This ATA lasted just over 2 months before the Line 1 port failed to make outgoing connections - incoming still

I followed the configuration instructions supplied by my service provider (Callcentric) for this particular model, and the adapter immediately connected went to work as soon as those were completed

Well, I took this ATA up to work and it worked just fine on our Asterisk PBX for a week or two, even on incoming calls.
