I have Call manager bussiness edition. And we are using cisco unity connection for our voice mail. I have a question how to remove voice mailbox for "Operator" and "undeliverable message" mailbox. I try to change their password in cisco unity connection administration. But when I want to access their voicemail from iphone handset, the password is invalid. I cannot access voicemail through web because I didn't buy those license. Is there a way to delete their voice messages, because this user is integrated with application user and directory number? Please advice. Thank you all for your help.
