I am a newbie with Nortel phone systems. I need to change phone numbers on several phones. When I try to change line assignments, even though I have unassigned them first, I get an error that I cannot make the change, (the line is in use).
What do I need to do to change line assignments. Due to internal problems I cannot relocate the phones.
