I have DSL with Verizon, there stech support people told me If I dropped my land line they would set up a "dry loop" for my DSL that would not take any bandwith away from the phone. My phones a cordless 5.8 GIG - 1base, and 4 handsets.
A friend of mine said this to me in an e-mail I do not have a clue what he was talking about does anyone else. Answer in 3rd grade english please

A good question for you to find out is how does your IP number (MagicJack) register (SIP/H323 Gatekeeper/Gateway/Proprietary)? The forums are your best bet for this info. Look for PBX connections.
Thank you everyone.
