emergency caller goes on-hook, otherwise, the ELIN is kept in use for
the duration of this timer.

Adding or Editing the
Emergency Defaults
The emergency defaults are used when there is no information in the
emergency response database for a emergency caller (phone IP address).
Typically, phone IP addresses are stored within ranges for a defined ERL.
If Emergency service settings are changed, (for example, the gateway IP
address or emergency digits) they will not take effect until the telephones
are power cycled. A simple logout/login of the telephone is not adequate
enough.
To add or edit the emergency defaults:
1 From the left-hand side of the Users main page, click the Emergency
Services heading.
The Emergency Defaults page appears.
2 In the IP Address field, type the IP address of a system-wide emergency
gateway.
3 In the Emergency Callback Phone field, type the phone number of the
contact person responsible for emergency situations within the
organization (for example, a security guard).
4 Click Save.
The Emergency Default is applied to the entire organization.
