[RPRequired]
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:

If MLPPDefaultServiceDomain is set to 'FFFFFF', the device
interworks the non-MLPP ISDN call to non-MLPP SIP call, and
the outgoing INVITE does not contain the Resource-Priority
header.
The valid value is a 6 hexadecimal digits. The default is "000000".
Note: This parameter is applicable only to the MLPP NI-2 ISDN
variant with CallPriorityMode set to 1.
