Hi. I read the brochure and the whole manually, sadly I haven't answered my basic questions Maybe someone can help me. I'm looking for a symple software that can be installed on my PC in my netword and use them to answer phone calls coming in from a magic jack line. I just need simple functions like put calls on hold and transfer them to a couple of other people. Is this the program I'm looking for? Does it need to install in every PC ? I appreciate any answer and / or suggestion!
