Thank you Laith and GokAy.
When i had DSL i had a splitter on the phone jack that split the signal for phone / internet, if that's what you mean by filter.
With Uverse i don't have those splitters.
If the DSLAM device is the "switch box" in my neighborhood, yes they did change the port for me, more than once i believe.
I have the phone jack on one side of the room and the internet (gateway) jack on the other side of the room.
From what i learned i need to get a phone jack next to the gateway (router) as magic jack needs to connect to both.
That's some re-wiring i'll have to somehow do.
I get about 350 TV channels and probably don't use more than 20.
I pay for 12Mbps Down / 1.5Mbps Up, although lately I'm getting 15 down / 2 up.
Unlimited internet and phone usage.
