So, you can have more than one plugged into your computer at once? That, I will admit, is interesting. Do they both use a single copy of the softphone software? Or, would you have two different panels open up? But, the fact that I must have a computer running in order to use the phone is still a bit much for me. I like my VOIP line to be totally independent of the rest of the network.
You can plug in as many Magic Jacks as your Internet speed can handle, I have had two plugged in at times and have had as many as three plugged in at one time while helping other people set up their MJ's....... One trick I have used is to get a few MJ's with local numbers in different states or areas of states and then forward those others to my cell phone or main MJ's and then people can call me with a local call from those areas no matter where we are in the world and for free to them....... It works great for friends and relatives all over the US that do not have computers, cell phones, free within US long distance or are not computer savvy and there are many of those out there that most of us computer people never think about.
As for Paul or others that prefer to spend many times more per year, that is their choice and I surely would also do that if I was using the VOIP for business but I cannot see paying for one month, more than it cost me for a whole year...... Just me, and maybe I am just too cheap and I would rather spend it on a good steak.
