Welcome to the Board!

The greetings that play are stored in a different mailbox from the one you use with your extension.

By default, this is mailbox 905 for after hours, 900 for regular business hours; your installer may have used something different.

Try logging into either of those mailboxes, and choose the option to listen to a recorded message in mailbox greeting management to verify if it is the greeting you want to change.

Sometimes the thoughts in my head get so bored, they go for a stroll through my mouth. This is rarely a good thing.
