Table 6-44: MLPP Parameters
Parameter Description
Call Priority Mode
[CallPriorityMode]
Enables MLPP Priority Call handling.
 [0] Disable = Disable (default).
 [1] MLPP = Priority Calls handling is enabled.
MLPP DiffServ
[MLPPDiffserv]
Defines the DiffServ value (differentiated services code
point/DSCP) used in IP packets containing SIP messages that
are related to MLPP calls. This parameter defines DiffServ for
incomingMLPP calls with the Resource Priority header.
The valid range is 0 to 63. The default value is 50.
Notes:
 The same value must be configured for this parameter and
the parameter PremiumServiceClassControlDiffServ.
 Outgoing calls are tagged according to the parameter
PremiumServiceClassControlDiffServ.
Multiple Differentiated Services Code Points (DSCP) per MLPP Call Priority Level (Precedence)
Parameters
The MLPP service allows placement of priority calls, where properly validated users can preempt
(terminate) lower-priority phone calls with higher-priority calls. For each MLPP call priority level, the
DSCP can be set to a value from 0 to 63. The resource priority value in the Resource-Priority SIP
header can be one of the following:
MLPP Precedence Level Precedence Level in Resource-Priority SIP Header
0 (lowest) routine
2 priority
4 immediate
6 flash
8 flash-override
9 (highest) flash-override-override
[MLPPRoutineRTPDSCP]
Defines the RTP DSCP for MLPP Routine precedence call level.
The valid range is -1 to 63. The default is -1.
Note: If set to -1, the DiffServ value is taken from the global
parameter PremiumServiceClassMediaDiffServ or as defined for
IP Profiles per call (using the parameter IPProfile).
[MLPPPriorityRTPDSCP]
Defines the RTP DSCP for MLPP Priority precedence call level.
The valid range is -1 to 63. The default is -1.
Note: If set to -1, the DiffServ value is taken from the global
parameter PremiumServiceClassMediaDiffServ or as defined for
IP Profiles per call (using the parameter IPProfile).
[MLPPImmediateRTPDSCP]
Defines the RTP DSCP for MLPP Immediate precedence call
level.
The valid range is -1 to 63. The default is -1.
