Using DND Modes via the IP Phone UI
If you add a DND key using the configuration files or the Aastra Web UI, you can
toggle the DND state using the IP Phone UI. Use the following procedure to
enable/disable DND on the IP Phone.
The following procedure assumes you have already configured a DND key AND
assumes there are three accounts configured on the phone.

Notes:
1. If there is no DND key configured or if it is removed, DND is
disabled on the IP Phone.
2. If there is only one account configured on the phone, then the
mode setting is ignored and the phone behaves as if the mode was set
to "Phone"
.
3. Using the Aastra Web UI, if you change the DND key mode to
"phone", all accounts synchronize to the current setting of Account 1.
