Cisco SPA112 VoIP Adapter

The Cisco SPA112 is the newest Analog Telephone Adapter from Cisco. A direct replacement for the Cisco PAP2T, the SPA112 provides the same voice quality and reliability that users have come to expect from Cisco ATAs.

The Cisco SPA112 is an Analog Telephone Adapter (ATA) with 2 FXS and 1 10/100 WAN ports.

Questions on Cisco SPA112

From Adam at 8/12/2014 8:00 PM

Q: I have a few of these devices and was wondering how I can use them to implement SIP with a legacy overhead paging system? After creating my extension and getting the device to register, the only problem I have run into is getting the system to auto-answer. Is there a special setting within this device to allow the voice stream to pick up and flow automatically?


A: The paging system would have to detect the ring and answer the call. The ATA does not have an auto-answer setting

Q: Are these ATA's compatible with a FAX machine and an analog phone/computer modem? We have an IP phone system, but do NOT want a POTs line from the local carrier

A: John,

You would set this up through the IP PBX phone system (SIP) in order to send and receive faxes within that interface as well as the SPA112.

From Doug at 5/23/2016 8:00 PM

Q: We have about 50 Cisco 7945's deployed to our production floor. Operators complain they can't hear the ringer. All the ringer/strobe devices I've found only work with analog lines. I don't want to have to run a second wire to each location to support analog. Can I plug an SPA112 into the PC jack on the phone and have it drive an analog ringer/strobe when a call comes in to that extension?

A: Hi Doug,

Yes, you should be able to do that from Analog to SIP in the web interface. You can still keep your existing lines if the PC jack you're referring to is Ethernet.

Please contact our sales department to further assist you!

good - with >= 1.3.1 firmware
we got a few of these on the first firmware, not so good. They have made big strides in improving the firmware- note - when you get one, login and go directly to Administration > upgrade firmware. Dont touch any other settings yet or it hits a bug that greys out the upgrade button.

We currently have about 10-15 of these in the field working well. Once in a great while they will need to be rebooted, but mostly working great.

Firmware upgrade page - current is 1.3.2:

Reliable / good call quality
First of all you need to get the newest firmware 1.2.1 Cisco has solved a lot of issues with this ... Once this is done the units have great. Call quality and a simple config and your good to go they just work to put things simple, nat'ed double nat'ed , no nat , internal network with nat ... have not had any issues ... We run a WISP and have some of these 4 - 5 hops out on our wireless network with no call quality issues.... Only issue I have really noticed is that setting these up off a config file doesn't always work 100% ...

Absolutely terrible ATA
This is the worst ATA I have ever used. The first firmware revision didn't even have working caller ID on incoming calls and the most recent firmware revision will sometimes hang and require a power cycle to bring back to life. Invoking the phone based configuration menu for setting or checking the IP address (by dialing ****) will sometimes cause the SPA 112 to reboot itself. This is just the start of the issues with this product... it also has DTMF issues, among other bugs, most of which are known issues in the release notes.

It is a beta quality device at best, and there was obviously little to no testing of the product before it was released.

Other ATAs work fine with the same ISP and VoIP provider.

Save your money and get a cheap Grandstream Handytone. It will work better. This device does not deserve the Cisco name.

FAX / Dial Tone loss
Save yourself time and energy. Stick with using an PAP2T-NA. It is a time tested device.
