Very strang thing happened. Installed a 400EC along with the ACS 6.0 Proc. Lines 1 thru 5 will display CID but line 6 will not. Checked configs even defaulted the system back to factory and still nothing. CID is sending when I move line 6 to another line port. COuld it be a bad port 6? I have never encounter a bad CID port before since port will provide dial tone and send adn recieve calls. Any ideas to late at night for me get another 400EC wonder if I did not program something?
