Router part limited to ~10 Mb/s throughput, so you probably want to use it in bridge mode
27 November 2014
Summary: Replaced a failed Sipura SPA3000 with this one. When I tested the router part they added, it limited my throughput to ~10 Mb/s but fortunately it has much more throughput in bridge mode so I could still have my entire LAN on a switch downstream from this box and let it prioritize my VoIP traffic.
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 ...
Summary: I'm using this device to provide a connection for a Cisco spa 303 ip phone to my home phone line (pstn) from my garage via a 500 ft. run of fiber optic cable. The adapter works as advertised, but if you aren't used to working with Cisco products and reading their instructional literature you'd...
Summary: This is a very nice piece of equipment, that I actually bought two of. I use the one for my second telephone line of [...] combining Gizmo5 and Google Voice for completely free incoming and outgoing local and long distance calls with basically all call features like Caller ID and Call Block.
Summary: I'm using the SPA3102 as a POTS to VoIP interface for Asterisk. So far I have only used the FXO port, so my review is based on that part of the device's functionality only. The unit works well.
Summary: I bought this ATA because i needed to make outbound calls through a PSTN gateway, using my Asterisk IP PBX. This device comes with one FXS and one FXO Port. For my primary purpose, the ATA does the job.
Summary: Cisco Linksys Pro SPA3102 is for advanced VoIP users because of the intense details in its firmware software. If you are newbie and just trying to play around with VoIP adapters, I would suggest to use grandstream or other generic brands as they are not that complex.
