Figure 38: Office phone displays the message Logged Out
When activated for Virtual Office by a remote IP Deskphone, your Office
IP Deskphone is logged out and no longer operational. If this is the case
when you return to your office, you can disconnect the remote login and
regain control of your Office phone. If you do not disconnect the remote
login, your Virtual Office session expires after a fixed period of time,
determined by your system administrator.
