Depending on the phone you will see nothing or an error message.

This device does exactly what I needed; it allows me to use a regular analog telephone as a VoIP phone.
DMBenG
It's had a couple of firmware updates to fix critical bugs since then.

This is an update to the reviews below (1/26/2013)
I upgraded to 1.2.1(004) and experienced problems similar to what others have described, w/ the device losing registration and requiring a reboot to get it working again. This was happening roughly every few weeks. I upgraded to v1.3.1(003) a little over a month ago and have not had a problem yet, so maybe they have finally come up w/ firmware that has the major bugs stamped out. Wish me luck...

This is an update to the reviews below (3/7/2012)
My opinion of this product has dramatically improved as Cisco has fixed bugs. They released a firmware update that fixed the caller id bug (1.1.0 (011)) and I just downloaded a beta release (1.2.0 (015)) that fixes the MWI problem. I've read some posts on the Cisco forums indicating there might be problems with the device frequently losing registration but I haven't experienced that issue.

I still feel it was inexcusable for Cisco to release the product w/ obvious and significant bugs, but they've been making significant progress in improving the firmware. Overall I can now say this is a nice product in my opinion. The documentation is very well written and very informative. I'm not particularly well-versed in the technical aspects of voip, but the manual provides clear and useful descriptions of each option, and I never felt like I was cluelessly guessing when configuring the device. I was on the verge of returning the unit I purchased but I am now pretty certain I'll keep it.

Cisco still has not created an official release of firmware that fixes the caller id bug, but there is a beta release available. Call 866-606-1866 and mention the caller id bug.

This unit does not send caller id information correctly. Depending on the phone you will see nothing or an error message. The older Linksys/Cisco PAP2 does not have this problem. According the cisco support forum they are working on a fix for this but this product should not be purchased until a working firmware is released.

I work for a non-profit, and we have a bunch of polycom conference phones that are analog. I actually like these better than the linksys boxes (PAP2-NA) that they replace. I read the horror stories on the reviews, but I didn't really have another option to go with so I pulled the trigger. So far I have 2 in production (2 spare) and they're going smooth. I know A guy that's using it to connect to a fax and surprisingly it's working awesome for him. Just don't forget to update the firmware! all of mine are on 1.3.2 and are going smoothly. I want to thank the other reviewers for giving me a heads up about the firmware. I love the amazon reviewing community!

I'll buy again

I bought this adapter several months ago. It's had a couple of firmware updates to fix critical bugs since then. As of now with the latest firmware it still locks up and requires a power reset every 1 or 2 days. A phone line is not something you want to be fiddling with on a daily basis to check and power cycle equipment. This is the worst purchase I've made in the past few years. I consider the device to be a waste of money. The firmware is still garbage a year after this product was first released.

We bought several of these units as my company has begun offering VoIP services to our clients. We used Sipura devices (the predecessor manufacturer of these devices before Linksys/Cisco bought them out) and they were quality ATA devices, the same as well with the previous line of Linksys branded ATA's.

However, with these Cisco branded models (SPA112 and SPA122), we've have quite a number of issues, even involved Cisco technical support, acknowledges several of these defects, yet months after still no firmware updates to resolve these issues. It's quite disappointing to see such a famous company as Cisco not standing behind one of their products.

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, T.38 doesn't kick in and it seems to always fallback to try faxing over a voice codec (ulaw)... This is okay if you have a fax such as a Brother, Xerox, Canon where you can lower the RX/TX speeds to 9600bps or lower, however, on fax machines such as certain HP fax machines where the RX/TX speed is not adjustable, it just doesn't want to work.

- Caller ID is very hit or miss, for the same caller, at times it will show the caller ID, other times it won't...

- MWI (Messaging Waiting Indicator light), when this option is enabled, if you have carrier provided voicemail, the indicator light stays lit even after you checked your messages and deleted them. (This issue was acknowledged by Cisco support, it's even part of the known defects in the PDF attached to the latest firmware update).

- Once in a while, the units stop responding and need to be unplugged/replugged to restore service.

If you need to be able to send & receive faxes reliably, I would recommend an ATA by Mediatrix instead. Their units are a bit bigger, but much more reliable in regards to faxing.

Hi Alex,
Thank you for the review. We've fixed every issue from the previous ATA T.38 faxing that we are aware of. Please make sure that you have the latest firmware. In addition, we will be releasing a new firmware that will address the lack- of-response issue soon. Please check for the latest firmware for the SPA 112 and 122 here: http://software.cisco.com/download/navigator.html?mdfid=282414109&flowid=5968

Thank you,
Cisco Small Business Team

I set up the ATA box with via talk. After performing a firmware upgrade it works pretty good. Looking at Cisco's blog page, I think they release this product too quickly without further testing. There has been several firmware upgrades with another one coming out next moth.
