i didnt unplug any other stations but i did try another phone there and got the same results. and that phone worked at its previous location. i didnt try the suspect at a diiferant location. not using dsl. didnt check current. most of the runs are about 75 feet or less to phone room. spectrum put two lines in phone room and two lines in office with high speed. go figure. all 4 lines on this set have the same problem. i will check on the other stuff tomorrow.
