I have a customer with a old BCM50A 1.0 that has a bad internal CO port. the software is also corrupt os software that doesn't allow programming of the auto attendant. If I get a new BCM50 6.0 can the keycodes be moved to the new system. I remember they use to move them when Nortel was in charge. You had to send the old system to Nortel.Thanks for any help.
