I found this thread but it didn't help.
-I have exts 366 and 822 both ringing when the external # for 822 is dialed. Dialing the external # for ext 366 results with a dead line.
-internal calls to 822, only rings 822. internal calls to 366, only rings 366.
-internal calls from 822, display 822. internal calls from 366, display 366.
I checked the answer DN on 366 and it's not assigned.
