If you intend to add a voice mail to the database this should be done before entering any manual settings.

As soon as you enter a manual setting it seems to take a copy of the original database settings and from then on the manual settings will never read the original database. So, any changes to the database after manual settings been activated will only work when Manual Settings = OFF.

So, if you use manual settings and need to add a voice mail number then add the number first and then enter manual settings. The device will then take a copy of the modified database and voice mail button will work in both settings (manual on/off).
