Emergency calls on your Remote IP Deskphone
If you make an emergency call while logged in to Virtual Office on a
Remote IP Deskphone, the call is placed to the local emergency service,
not to your home office emergency service.
Note: Some IP Deskphones are configured as Virtual Office-only
telephones and have no assigned DN. However, these IP
Deskphones can still be used to make emergency calls. “Emergency
Calls only “ is displayed on the IP Deskphone display when not
logged in to Virtual Office. When the phone goes off-hook, dial tone is
available for emergency calls only. All other calls are restricted.
