We had a user (user1) with ext 6000, they left the company and a new user (user2) came in. We were unable to delete the user through gui, we did it through cli. Now when someone calls 6000 it doesn't go to user2's vm mailbox, instead we here user1's greeting. Although user1 is no longer in the system.
If anyone has encountered this issue or can suggest any troubleshooting steps, please let me know.
