Summary: This device does what it supposed to do. I use it to connect an IP PBX to a PSTN line. It works. There are a lot of configurable parameters, probably way too complicated for a non-technical person. Documentation is decent, but not great. Don't expect Cisco to put out any more firmware update on this product, as this product has been around for a long time. The first unit that I received was broken. I had to ship it back to Amazon and get a replacement.
Summary: i'm still trying to configure this thing and whenever i try to access the website i can't. it keeps on giving me an error. can you help me configure it. i rated this item just to get through, because since i haven't been able to set it, i don't know how it really works
Caller ID is not RFC compliant, not 3CX compatible...

Summary: The SPA3102 is not SIP RFC compliant. It passes PSTN callerID unquoted as part of the From field sent to the SIP server. Cisco has not updated their firmware on this device to be RFC compliant as of this review. This prevents 30% of my inbound calls from completing as a result. If it weren't for this one issue, I would give it 5 stars. The product is easy to setup, has many configuration options and can even be autoprovisioned/configured by software PBX such as 3CX.
Summary: Worked as expected except that I found out after purchase that although it will connect a POTS line to a VOIP telephone system, it does not support Call-Waiting over the POTS line. The POTS line is only considered for failover and does not support all the features of this device.
Summary: I generally like this product, but there's one problem with it. Likes: Lots of options, VOIP stuff (the most important stuff) works fine. Dislikes: The PSTN functionality is very poor. If the unit has no power, it just passes the PSTN connection through, which is fine. Kind of a 'fallback' mode if there's an electrical outage. However, if its powered on, the PSTN audio has a distinct and annoying echo.
Excerpt: Si tratta di un prodotto ideato originariamente dalla Sipura spa e poi più capillarmente commercializzato e diffuso dalla Linksys. E' una scatoletta piccola, quadrangolare (l x a x p = cm. 10 x 10 x 2,5), grande forse meno di un modem adsl, che ha, sul lato frontale, quattro led verdi, che si accendono e spengono in corrispondenza del funzionamento delle quattro prese retrostanti; queste sono: 1) la presa per l'alimentatore; 2) la presa per ...
Pros: Prodotto completo sia per linea pstn che voip
Cons: Inesistenti istruzioni di settaggio, difficoltà per l'acquirente
