User's Manual 67. Configuration Parameters Reference
Version 6.8 925 Mediant 500L MSBR
Parameter Description
For FXO, CAS, and ISDN: 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
458.
The list can include up to four different numbers, where each
number can be up to four digits long.
Example: EmergencyNumbers = ‘100’,’911’,’112’
Web: Emergency Calls Regret
Timeout
EMS: Emergency Regret Timeout
CLI: emerg-calls-regrt-t-out
[EmergencyRegretTimeout]
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: This parameter is applicable only to FXS interfaces.
Multilevel Precedence and Preemption (MLPP) Parameters
Web: MLPP Default Namespace
EMS: Default Name Space
CLI: mlpp-dflt-namespace
[MLPPDefaultNamespace]
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.
 [1] DSN (default)
 [2] DOD
 [3] DRSN
 [5] UC
 [7] CUC
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 472.
[ResourcePriorityNetworkDomains] Defines up to 32 user-defined MLPP network domain names
(namespaces). This value is used in the AS-SIP Resource-
Priority header of the outgoing SIP INVITE request. This
parameter is used in combination with the
MLPPDefaultNamespace parameter, where you need to enter
the table row index as its value.
This parameter is also used for mapping the Resource-Priority
field value of the SIP Resource-Priority header to the ISDN PRI
Precedence Level IE. The mapping is configured by the field,
EnableIp2TelInterworking:
 Disabled: The network-domain field in the Resource-Priority
header is set to "0 1 0 0" (i.e., "routine") in the Precedence
Level field.
 Enabled: The network-domain field in the Resource-Priority
header is set in the Precedence Level field according to
Table 5.3.2.12-4 (Mapping of RPH r-priority Field to PRI
Precedence Level Value).
The domain name can be a string of up to 10 characters.
