Here,s the deal. I have a user with CME. His secretary has 7940 (ephone 1 in config) and ATA (ephone 24) with one shared line (ephone-dn 1). ATA has Panasonic cordless on its port
They want both 7940 and Panasonic to ring simultaneously. This works fine except when the phone that is answered is Panasonic. Then the other incoming call doesn't ring on 7940 (I know this is expected behaveour), I only get Call Waiting indication on Panasonic. Customer wants that second incoming call rings on 7940. I tried with two DNs with different preferences, but the second call never goes to the second DN since it doesn't return busy signal, but Call Waiting. I tried to switch off Call Waiting on Panasonic but with no luck. Any suggestions how to set this up?
Here is the configuration:
ephone-dn 1 dual-line
