I have an extension that is stuck in the "connecting" mode. I. E. when you pick up the receiver you hear scratchy noise then remote ringing as if you had dialed a number. I have changed handsets, plugged in at the switch with all downstream wiring disconnected, changed the extention number. I still get the same result. I have looked at LOCATE FEATURES EXTENTION xxxx and nothing is listed.
Any further ideas would be greatly appreciated! Thank you.
