netTALK DUO

Ordered this to compare against Magicjack .I prefer the call quality of netTalk DUO and the fact it can be connected to router directly not needing a computer on at all times .Setup was very simple .There's not alot of area codes available yet for Canada , Here's the list of Canadian area codes for nettalk duo as of March 2011 :

BC : 778 ( Vancouver)
AB : 587 - 403
ON : 647 - 289 - 613 - 705 ( Toronto,Mississauga,Ottawa,Sault Ste. Marie )
QC : 438 ( Montreal)

Only gave 4 stars simply because of the lack of canadian area codes or else would easily be 5 .

You get a local area code, voice mail (emailed to you) or can dial *98 to pickup, call waiting, 3 way calling etc. etc., free calls in USA & Canada. All for only 39$ a year(Canada). Cancelled my Rogers home phone. Plug in Duo's telephone line into one of my home landline telephone outlets and back fed to all the phones in the house. Initially planned to use the Nettalk Duo for traveling when wintering in the USA but now its my home phone.
My home alarm monitoring system works too with the Duo which the MajicJack did not (note had to call the monitoring company to program to call their direct number without #1 in front of it rather then a toll free number)
The advantage this unit has it's own power not relying on your computer. But can also connect by computer USB.
I tried the USB connect but on occassion needed to be unplugged and plugged back in when Computer went to sleep.
It needs Windows OS to use the USB. I use Parallels 6 on my MacPro to run the USB connection. Notwithstanding the Ethernet connection is the best way to go for reliability.
I love that once you plug everything in incl your corded phone Duo connects within about 5 seconds and your phone rings once to let you know all is working.
Reception is excellent with on occasion you can hear your voice echo on a call. The other party can't hear it but I usually just call back if it's going to be a long call.
There is also the odd 1 second break in the reception but that maybe my internet since my Brother in Vancouver doesn't have the problem on his Duo.
Works also when plugged into my cheap portable wireless router/repeater/accesspoint CNet CQR980 which has two Ethernet ports. (Used for travelling and sharing in hotels or any free wireless hotspot. Router works flawlessly with the Duo on wireless mode. My plan is to connect the Duo to Virgin Mobile wireless Hotspot by pairing the CNet router with the hotspot while traveling wintering in the USA. This way can have a Duo phone, ipad, iphone, sharing one hotspot without tethering)
Downloaded their free iPhone App which also works great. They are working on your dedicated Duo phone number will ring on your iphone with this app when you have WIFI. For now free outgoing call only on this App.
To set up or pickup your voicemail dial *98 and follow the prompts.
Although I am still working on a few issues all in all it is a great product that I highly recommend.
Enjoy!!

I have it connected in London, ON; there are only limited area codes available. I have it connected via Rogers internet. It is good when it works - sound quality is reasonably good and clear - better than the cell phone at times.

The problem is that there are times when we cannot dial out - we have noticed that this is typically when calling a Rogers phone number (such as cell phone, landline) - you just hear an engaged tone when we know that the cellphone is not engaged (I have tried to call my own 2 Rogers cell phones). There is no problem calling other numbers at such times or receiving calls including Rogers incoming. Not sure what the problem is - I wonder if Rogers somehow blocks these outgoing calls. (And there are no issues with out internet connection at these times.) As a result the reliability is questionable and it cannot be relied on as the sole phone.
