Emergency Numbers
Public telephone networks in countries around the world have a single emergency telephone
number (emergency services number), that allows a caller to contact local emergency services
for assistance when necessary. The emergency telephone number may differ from country to
country. It is typically a three-digit number so that it can be easily remembered and dialed
quickly. Some countries have different emergency numbers for different emergency services.
You can specify the emergency numbers for contacting the emergency services in an emergency
situation. You can dial these numbers when the phone is locked. For more information on phone
lock, refer to Locking/Unlocking Keypad on page 30.
Note
To specify emergency numbers via web user interface:
1. Click on Features->Phone Lock.
2. Enter the emergency services number in the Emergency field.
For multiple numbers, enter a comma between every two emergency numbers. The default
emergency numbers are 112, 911 and 110.
3. Click Confirm to accept the change.
Then you can dial the emergency numbers when the keypad is locked.
Contact your local phone service provider for available emergency numbers in your area.
The IP phone also supports the emergency dialplan, which allows users to make emergency calls
if the phone is locked or unregistered. For more information, contact your system administrator.
Block out is configurable via web user interface only.
Block out is applicable to all the handsets registered to the base station.
