Summary: I got the SPA3102 in 2010 to use the free Asterisk PBX to bridge to my Verizon land line for non-SIP Trunk backup in my VOIP system. The Telco connecting FXO on this little box provided the bridge to the PSTN for that backup.
Pros: I as able to integrate this FXO/FXS module into my home asterisk server very easily. I was pleasantly surprised to see that it actually pushed the caller ID info to the analog phones without any extra configuration. I guess that's the power of voip/Asterisk.
Cons: Analog ringgers sound a little funny. Maybe I'm trying to ring too many phones simultaneously. Not really a con, just an observation.
Summary: These devices are very reliable and always ready for action. Phone calls are always crystal clear, just like a land line. Don't believe the hype on other reviews. If you set the perimeters in the settings of the device properly, the device will work like a charm.
Pros: The OS is feature rich. You control whatever you want. One good feature is that the lights on the device will always let you know if you have up-link to the internet or not. In other words, if your modem is not getting internet signal, the lights will be off on the VoIP line. We use the router on...
Summary: Has worked well so far, no reboots, no crashes. Does get a little warm, but should not be a problem. I'm running this with Asterisk setup. Definitely requires a person either knowing what they're doing, or be open to do researching online for getting this to work as needed.
Pros: Does the job well. Nice build quality. Lots of manual customization options (though this could be a CON, depends how you look at it). Tons of resources online on getting this to work.
Cons: When placing calls from with line1 or SIP phone to PSTN, echo may be present for the local party (the remote party seems fine). Took quite a bit of fine tuning to get it to a reasonable level where it doesn't bother me. Upgrading firmware without a PC could be tricky (though there are ways to do ...
Cons: you call a cell phone or an automated machine they can't hear anything from you. Takes long before you can get the right information on how to configure it. Tried to check support on website but couldnt find any help. You actually have to PAY to get some support Avoid this and get yourself someth...
Summary: Do not buy this item if you want to use it as a router. Extremly poor performances. My 20Mbps connection drop to 7 Mbps when i connect it to my computer, and the SPA keep rebooting as soon as it's stressed a bit (if you use Torrents client for example).
Pros: Works well (for ATA purpose) once you have upgraded the firmware.
Good choice for single line with multiple SIP providers

Summary: I like this model for its gateway feature so that my wife can pickup the phone and just dial to make either local, NA or international calls without switching phones or any unplugging/plugging. I have some difficulties setting up.
Summary: This is a great device for VOIP. It allows practically anything that you want to do voip related but beware: it's a very powerful device which has LOTS of options for configuring. But at the same time, that feature is at the same time the biggest flaw: it's complicated to make it work.
Summary: I purchased this product 2 month back. It works great. The great feature of this product is you can have one VSP incoming and upto 4 different outgoing VSP. My bill does not go above $5-$7 a month even though I make a decent number of calls every month and no service charges, taxes, etc.
Summary: I am using this mini monster to connect my line PSTN with internet and my brothers from Spain can do local calls thanks to this equipment. I recomend it if you want a nice gateway for VOIP. (it have a FXS and a FXO modules).
