Refurbed ksu, install 12=4=13. Customer says low volume when calling in on lines 1 & 2. Telco lines test uniform over the 6 pots lines. I know i can move the lines to spare co ports. This is the 3rd cabinet in the past 3-4 years with the same issue. Is there something more i can do or just move the line ports.

Thanks Gary S (still home on crutches)
