I have
freephoneline.ca as SP1 and Google Voice as SP2. I have a Telus prepaid cell phone that gives me unlimited calls to and from 1 number for 10 bucks per month. I assign that to my FPL 1 number unlimited. When I make outgoing calls I call into my OBI110, press 2 and make all my outgoing calls for free! If I need to call the US after I press 2, I press**2 and dial the US phone number. I program this into my contacts with the pause feature. It's FANTASTIC! As long as I am in my local calling area which I am it's a go. Unfortunately incoming calls are 20 cents per minute, but I just don't answer them. I see the CID and call them right back, kinda like a pager. I don't text but you could buy a text package for a few bucks more per month. So with the OBI and the Telus 1 number unlimited I am getting unlimited calling to north america for 10 bucks per month!. Thanks OBI!
I have my wife on the same setup. Freephoneline is exactly that FREE! You pay a one time 50 dollar setup fee but after that there are NO monthly charges! So to put it all together I have my home phone system which gives me my local phone number and the ability to make and receive calls to north America for FREE! Add mine and my wife's cell phone setup at 10 bucks each per month and the grand total I am paying is 20 bucks per month for 2 cell phones and the home phone plan! And of course the call quality on both FPL and GV is outstanding, really no audible difference from a regular POTS line.
I should mention that I have 3 OBIS, one for home, one for my wifes cell, and one for my cell, just because of CID issues. Hope this helps someone else out there to get around the ridiculous costs of telephony. It seems people just accept paying 50/month for their cell phone and 30ish/month for their landline, but the OBI makes all that history! FANTASTIC little device! For us that used to amount to a 130 plus bill every month. 3 OBIS cost app 120, 2 FPL lines cost 100 for a total of app 220 dollars...so my little system has more than paid for itself after just 2 months! That's a 1st year savings of 1220 dollars, second year and every year after that of 1440 dollars! Times are tough right now so every little bit helps.
