Parameter Description
MLPP (Multilevel Precedence and Preemption)
(
Note:
For additional MLPP parameters, refer to ''Supplementary Services'' on page 159 .)
MLPP Default Namespace
[MLPPDefaultNamespace]
Determines the Namespace used for MLPP calls received from
the ISDN side and destined for the Application server. The
Namespace value is not present in the Precedence IE of the PRI
SETUP message. Therefore, the value is used in the Resource-
Priority header of the outgoing SIP INVITE request.
ƒ
[1]
DSN = DSN (default)
ƒ
[2]
DOD = DOD
ƒ
[3]
DRSN = DRSN
Default Call Priority
[SIPDefaultCallPriority]
Defines the default call priority for MLPP calls.
ƒ
[0]
0 = ROUTINE (default)
ƒ
[2]
2 = PRIORITY
ƒ
[6]

ƒ
[8]
8 = FLASH-OVERRIDE
ƒ
[9]
9 = FLASH-OVERRIDE-OVERRIDE
If the incoming SIP INVITE request doesn't contain a valid priority
value in the SIP Resource-Priority header, the default value is
used in the Precedence IE (after translation to the relevant ISDN
Precedence value) of the outgoing PRI SETUP message.
If the incoming PRI SETUP message doesn't contain a valid
Precedence Level value, the default value is used in the
Resource-Priority header of the outgoing SIP INVITE request. In
this scenario, the character string is sent without translation to a
numerical value.
Preemption Tone Duration
[PreemptionToneDuration]
Defines the duration (in seconds) in which the device plays a
preemption tone to both the Tel and IP sides if a call is
preempted.
The valid range is 0 to 60. The default is 3.
Note:
If set to 0, no preemption tone is played.
