A phone line isn't long enough to the conference cable. So I would like to extend it with a cat 5 cable.
However, there is some type of module connected to the end and the wires are colors I am not familiar with. When I take the module off I'll have five colors: Green, Brown, White, Red, Blue, and Black. It looks like the white and green are used primarily.
Which wire colors would I use on a normal cat5 cable, to connect with this legacy cable?
A picture is attached so you can see what I am working with.
At the end of the cat 5 I need it crimped to a RJ11 since it is a POTS line.
