I am a novice Nortel programmer (novice means I follow instructions from a manual well.) I have a situation where a port on a MICS went bad, so I cross connected the station wire to the next available port. His extension went from 223 to 243. He has a DID number, that says 148 and then the 7-digit DID number when I inspected the button on the old phone. How do I get that to the new phone? Or is there a way to just swap the extensions in software? Do I need to know what release of MICS it is to accomplish this? The guy is without a phone till I figure this out so any response is appreciated. Thanks. Diana
