Ok so I have a weird one and I cant seem to locate the issue, I have a customer with a much older OS7100 (about 11 years) and it has the 4 lines ring and then go to AA I have them going to group 501 and then fail over to 519. lines 1,3,4 all go to the correct AA message but line 2 will always go to a default message. What am I missing?
