Currently the option Call me to play or record the selected greeting… within your Unified Messaging Options in Outlook web access does not work. Follow these steps to record a message:
To enable your voice-mailbox you need to forward all calls to 39990 (not 29990 as used to with Xpressions). To disable just disable the forward.
How to configure a forward to your phone can be found in https://www1.ethz.ch/id/services/list/voice/optipoint_500.pdf for the ETH standard phones. It is also possible to configure one of the quick dial keys of your phone to allow to enable/disable the forward function very easy. Just seek the manual for the specific options. A short guide follows here in the future.
