I hope there is someone to help me with this. The phone company just left a new jack to install to replace the old one that wasnt working when i opened up the wall jack this is what i found pic 1 i have tried endless configurations and nothing. Each jack has the colored wires in a different configuration Im totally stumped any help would be appreciated. The wires are old very old i think but what is totally confusing is that there is also a cable with only three wires with a red green and yellow no blue only a rip cord. If the home is a little more modern then it is probably wired with Cat5 cable. This has 8 cables and can be a little confusing.
