I currently have 61xx and 62xx extensions. I have added 63xx extensions and mailboxes. I can log into the mailboxes,but only get system message (enter extension number)after 4 rings instead of user greeting. Get same greeting when pressing message button instead of asking for password.I assume its a dial plan issue, but not sure if the problem is on the AAM or CM. I am new to Avaya, so any advice would be appreciated.
