Voicemail has been locked by the administrator

[sirios34]

I have a customer that every other day or so their voicemail gets locked. It doesn't happen to call the mailboxes just a one or two at a time. I have to reset the password every time. Does anybody know what can be causing this?
They say they are putting in the right passcode for the mailbox as well.

Cyber attack? Anything in the logs?

It could be an hack attempt.
Do you have a toll free number that rings to VM after hours?
Check your SMDR logs for some odd calls after hours.
You may also want to be sure that your VM ports cannot place any outbound calls unless it's going to a system speed call.
This will stop a successful hack from being able to dial out of your PBX.

BTW: be sure that your default admin passwords have been changed.

I have no remote access to it, so I went onsite to check the logs just to find out smdr was not on for external calls.
They dont have a 1-800 number. The password is changed.

Thanks for the replys

Dial into one of the affected nukmbers after hours and see if you are getting voice mail (wait till the no answer period to make sure).

Its the system logs you need to look at so if no remote access then you will need to go back on  site.....

There are VM logs.   They could be checked also.
You'd be looking for a login into one of the mailboxes with a problem.
