I have a trouble on a new system install where all 4 CO lines start ringing in with phantom ringing at intermitten times during the day, I tested the lines at the customer interface yesterday on the outside of the building and on ALL their lines I picked up a local AM radio station, the station is 5 miles away following the RR tracks.

My question is does anyone know if the Lec (AT&T) has the responsibility to surpress this or is it up to me to try to use filters from Mike Sandman etc.

Any info would be greatly appreciated.
