Question: Will this work with a rotary phone for dialing, or is it touch tone only?
Document: I've been using two of these devices for a couple of years now with no problems--configured and forgot. One I configured in the US and sent overseas for zero-cost local dialing to an in-law's house in Central America. The device in my house is hooked to the house phone circuit (which I first disconnected from the Telco line--advised because a telco line can have current even without service). My device rings four house phones with no problem at all.
Try several time to get my phone to work . No luck and on help from Cisco
For phone service, works like a charm! Set it up with callcentric.com. Very easy! Sound quality better than cell, but not as good as land line. In my book, that's excellent! I am still working on getting the fax function to work.
The Linksys SPA2102 Voip Phone adapter with Router is an amazing product. It works very well as it is supposed to do. My two voip's lines work fantastic, the sound is clear and I have excellent phone calls on it. Also, my internet speed is not disturbed when I am in a phone call. Easy to set up. I love this device! I strongly recommend it.
I purchased this unit to use with Voip.MS service after my phone power service came up for renewal and the renewal price was much higher than we signed on for. The adapter works great so far but did require some tweaking to get it working great. I would not recommend this item for non computer people but otherwise it seams to work fine so far.
When I switched to Callcentric as a VoIP provider, I picked this beauty up about 1-1/2 years ago and it's worked flawlessly since then. It's got WAY more configurable settings than I need, but it's exceptionally easy to setup. I'm running it at home as a simple POTS connector over FiOS and the call quality is superb. Configuration is as simple as connecting a standard touch-tone handset to the RJ-11 jack and walking through the menu options using the handset's keypad.
Yes, the product was exactly as described. It was delivered in a timely fashion, and in the manufacturers packaging as seen on the web ad. I have internet phone service through an independent company, and I needed a product that served as a router for my phone service, and wireless router for my laptop. This router does not have these capabilites. It has no wireless functions at all, and does not work well with baseline internet services; the one for $19.99.
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.
The router also handles faxing fairly well and I have it hooked up to my home security system which has an internal modem to dial out to my alarm company, and it works fine for that too, but faxing and dial type modem success may depend on your voip provider. Some do not support fax tones and protocols. I like the indicator lights so I can verify my connection status.Happy dialing!
All my other telephone sets, cordless or corded, work well with the SPA-2102, especially my multi-handset cordless Vtech DECT 6.0 system.
Answer: This devise  will be a bridge allowing the voice system in your network. Yes a rotary phone should work as well.
