Product Description

Inexpensive, easy to install and simple-to-use, the SPA2102 connects a standard telephone or fax machine to IP-based data networks. VoIP service providers can offer residential and business users traditional and enhanced communication services via the customer's broadband connection to the Internet.

The SPA2102 features two POTS (Plain Old Telephone Service) ports to connect existing analog phones, fax machines, or to a PBX system. The SPA2102 includes 2 100BaseT RJ45 Ethernet interfaces (LAN-WAN) to connect to a home or office LAN, as well as an Ethernet connection to a broadband modem or router (WAN). Each SPA2102 service line can be independently configured via software controlled by the service provider or the end user.

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? :)

Works well with Gizmo5 and Google Voice. Easy to configure. There are only 4 things you have to change in the options page, so don't worry about the 200 other option fields for advanced users. The configuration below is from the Gizmo5 support page. I only changed the lines below where I've added an astrisk:

SIP Settings

* Display Name (your Gizmo5 user name)
* Proxy Server (Host): proxy01.sipphone.com
Proxy Server (IP): 198.65.166.131
Registration Server: proxy01.sipphone.com
* SIP Port (UDP): 5060
STUN Server: stun01.sipphone.com
STUN Port: 3478
* User ID: 17471115555 (replacing with your 1747)
Auth ID: 17471115555 (replacing with your 1747)
* Password: (your gizmo5 password)

The Gizmo5 link for configuration is below.

This works well, and was easy to set up. I just followed the directions from the VOIP provider I chose (callcentric), changed a few settings, and that was it. Worked immediately. Haven't had any problems with it.

I'm sure if you know everything about VOIP, you could change all sorts of other settings (there are hundreds), and do clever stuff - but I just wanted this for a simple, cheap phone line.

I originally leaned toward this former Sipura product, now owned by Cisco based on 3 yrs of positive feedback from many VoIP users. I am not a huge fan of Cisco for several reasons, but D.Schumann's review here made the final decision for me. It does everything as advertised, but wait! There's more! ;-) I have been able to configure two lines completely differently. I design massive VoIP systems for global enterprises, and I like to test some of my theories at home using an Asterisk ACD/PBX and IVR. I can run my home and office off the two lines, then on the weekend, change Line 2 to be fully SIP enabled, with no legacy PSTN TDM connectivity. So my testing, albeit very tiny little test system, appears exactly like my millions of call/day systems. This ATA has prevented me from dropping a thousand or two on an enterprise level media gateway. I only need those for volume testing, and that's done in our labs, so I am probably the happiest SPA2102 customer in the world today! This VoIP professional gives the SPA2102two thumbs up. For a normal two line household, you should be able to tune the SPA2102 with a good VoIP provider to have better call quality than with a legacy carrier and certainly better than any cable digital phone service.

I had been paying Qwest, my local phone service provider, almost $40.00 a month for a basic phone line with caller id for over 25 years. Other common options like Skype, Magic Jack, or Comcast did not look like they would allow much flexibililty, so I bought one of these unlocked voip routers. I settled on voip.ms service because they allowed me to port my number, but this voip router will work with a huge variety of other voip service providers. I would say that the SPA2102-NA is practically the standard method now. Your research will probably confirm this. The -NA on the end confirms an unlocked router meaning that it is not pre-configured for any specific voip provider.

Set up on this voip router was pretty straight forward for me, but I'm fairly technically inclined. You may need the assistance from your local teenager to help you figure it out. You'll find that most of the voip providers have a setup example page which will usually include the settings for this router or a similar model. Since it provides for two separate phone lines and service accounts, I also had it configured to work with Gizmo5, but Google recently phased that service out.

I have mine mounted on a wall in my basement where my main phone line comes into the distribution panel, that way, I can have all of my home phones connected to it. I plugged this router into my home network router and when I want to make changes on it, I temporarily unplug one of my computers from my network switch hub and plug it directly into the LAN port of the SPA2102.

I received a locked SPA2102 (SPA2102-AN) from Save the Earth Books. Note that the unlocked model of the SPA2102 is SPA2102-NA. When I contacted the seller and asked for an RMA number, they initially said that I could fix the problem with a download from linksys.com. This is not correct(you can not update the firmware on a locked device), and when I pushed back, they agreed to refund and pay for return shipping. I am shipping back the item today, and will order from a provider that guarantees an unlocked device.
