 RJ11 to RJ45
I just got VOIP. The box sent to me only has RJ11 outputs. My house is brand new. They ran Cat5e all over for network and phone. The phone lines are punched down to a block with all the other phone lines. The incoming line from the landline phone company is Cat5e and it is punched down onto the block with all the other phone lines on the #4 block. I want to take out the landline punch down, and put in the VOIP. The VOIP has 4 wires, the landline has 6 wires. These should be the same signal, but how do I get the VOIP onto my phone block?

Dear Kenneth,

Once VOIP is installed the telephones only use typically 2 wires which are on pins 3 & 4 of and RJ-11 or Pins 4 & 5 of a category 5e jack (wired as either T568A or T568B). Typically in the cord it is the Green & Red colored wires. Connect this to where the land line cable Bl/Wh-Wh/Bl pair formally connected.
