protocol, according to the Bellcore GR-350-CORE standard.
You can also configure the functionality per specific calls, using
Tel Profiles. For a detailed description of the parameter and for
configuring the functionality in the Tel Profiles table, see
Configuring Tel Profiles on page 439.
Note: If the functionality is configured for a specific Tel Profile,
the settings of the global parameter is ignored for calls
associated with the Tel Profile.
Defines a list of "emergency" numbers.
For FXS: When one of these numbers is dialed, the outgoing
INVITE message includes the SIP Priority and Resource-Priority
headers. If the user places the phone on-hook, the call is not
disconnected. Instead, a Hold Re-INVITE request is sent to the
remote party. Only if the remote party disconnects the call (i.e.,
a BYE is received) or a timer expires (set by the
EmergencyRegretTimeout parameter) is the call terminated.
For FXO, ISDN and CAS: These emergency numbers are used
for the preemption of E911 IP-to-Tel calls when there are
unavailable or busy channels. In this scenario, the device
terminates one of the busy channels and sends the emergency
call to this channel. This feature is enabled by setting the
CallPriorityMode parameter to 2 ("Emergency"). For a
description of this feature, see 'Pre-empting Existing Call for
E911 IP-to-Tel Call' on page 570.
The list can include up to four different numbers, where each
number can be up to four digits long.
Example: EmergencyNumbers = '100','911','112'
Defines the time (in minutes) that the device waits before
tearing-down an emergency call (defined by the parameter
EmergencyNumbers). Until this time expires, an emergency call
can only be disconnected by the remote party, typically, by a
Public Safety Answering Point (PSAP).
The valid range is 1 to 30. The default is 10.
Note: The parameter is applicable only to FXS interfaces.
Determines the namespace used for MLPP calls received from
the ISDN side without a Precedence IE and destined for an
Application server. This value is used in the Resource-Priority
header of the outgoing SIP INVITE request.

Note:

If the ISDN message contains a Precedence IE, the device
automatically interworks the "network identity" digits in the IE
to the network domain subfield in the Resource-Priority
header. For more information, see Multilevel Precedence and
Preemption on page 571.
