One of my extensions started having distortion (noise from speaker phone all the time). I moved the phone KXTD7230 to another line and it was working fine. Put a different phone on the bad extension and the bad extension was dead. Powered down and back up with the problem persisting. The problem extension is on a 8 extension expansion card. What's the best way to fix this? thanks, Ken _________________________________________________________________ KX-T Mailing list --- http://kxthelp.com/ Subscription changes: http://kxthelp.com/mailman/listinfo/kxt
