IP Office 9.1 security settings
With 9.1 there are a lot of changes made to add more security to the system.
One of them is is that you are forced to change the default passwords at the first log in.
One exception is when you upgrade from a lower version, you will keep your current credential until you reset the security settings.
So when you want to open the config of your system then you will get a new screen where you are asked to change the default credentials.
Once you have done this and clicked on the OK button then you will get three notifications that the new passwords are set.
