Hey guys I work in a commercial building where the cabling (cat 3) is a horror. Anyway there is another issue I have to deal with that is the cleaning crew or the workers there spilling liquids on the phone jacks. No one claims responsibility so it is to me to get the voice working again. So far I can tone out the line but no voice. When I pull the wires out of the jack and stripped them, I can successfully test with my butt set. But the old jack is useless for voice no matter how I set up the clean wires (also checked the jack for corrosion-none I can see). So I used a one port cat5e quick jack and i punch down the two wires and voice! Yet I am wondering was there anything else I can do to try to save the old jack?
