My wife has been bugging me for years to get a home phone, however, I just haven't been able to constitute the cost / usage of the phone with our cell phones. Well, i think with home automation in my mind now, then I can justify the cost 
I have not decided on a software yet for my Home Automation, and I will research for one that enables phone commands. One that I do know will work with phone commands is http://www.automatedliving.com/, but I'm sure there are tons out there.
My question really comes with what type of phone technology will work. I really like the idea of getting this http://www.magicjack.com/4/index.asp and only paying 20 bucks a year; however, I want to ensure using that will work with whatever program I choose for my HA.
And, is this something I should be asking specific program companies? Or, has anyone else used the magic jack in their HA setup and found it to work ok?
