Thanks for your response JJ. I have not tried magic jack yet, I have a trial coming in the mail. If I have trouble with it similar to what you described, I will definitely be kicking it to the curb. From what I've heard it's pretty good, but I've only heard from less advanced users.
I did some research and I saw some other adapter options, it looks like this one seems to be the one I am most interested in currently >>http://www.newegg.co...239&Tpk=SPA-3102
It would be preferable to combine the VOIP into the SOHO server (purely looking at cost in that statement), but it may not be practical in many different senses. A hardware solution will offer more reliability and with an FXO port, I will be able to combine it with a POTS line which is very interesting to me.
I am seriously considering many different aspects of this, I may end up changing the design a lot, but in the end I will definitely be using a SOHO server pc of some sort, it's just the types of things I'll put on it I am still considering.
I may end up with a setup more similar to this dual internet gateways >> SOHO router >> off the shelf router >> network, but still working out the kinks. Apparently, what I'm trying to accomplish hasn't been done before, and no one seems to care lol.
It's my thought that it can be done with advanced iptables scripts etc but my knowledge is limited in the area of making my own. Perhaps this project will be a revenue for me learning these things, but I would prefer not expend the energy if it will not payoff ultimately with the setup I intend.
We'll see what happens, I'll keep this post updated as I progress
