Re: Magicjack connection What you are calling a "splitter" is best referred to as a "Switch" (switch/YES - hub/NO). Plenty of available options. Try to get from a reputable vendor (Linksys/Cisco/Netgear...). After a quick search, this is a decent option: NETGEAR 5 Port Gigabit Desktop Switch (GS605AV) at a good price.
Absolutely possible - be careful - you just might love this stuff.
That's "MISTER" Kafir to you.
