A customer reported an issue regarding a user where if she tried to listen to her voicemail messages she would get “Mailbox is in use”.
This issue normally happens if any TUI session or VoiceView sessions are open in any other phones having access to that GDM or the ports have become stuck or busy.
To resolve the issue, login to CLI of CUE module and issue this command:
voicemail mailbox unlock owner Natasha
voicemail mailbox unlock telephonenumber 6311
