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:

SIP User's Manual
MLPP normalized service domain string. If the device receives
an MLPP ISDN incoming call, it uses the parameter (if different
from 'FFFFFF') as a Service domain in the SIP Resource-
Priority header in outgoing INVITE messages. If the parameter
is configured to 'FFFFFF', the Resource-Priority header is set
to the MLPP Service Domain obtained from the Precedence
IE.
The valid value is a 6 hexadecimal digits. The default is
'000000'.
Note: This parameter is applicable only to device's using the
MLPP NI-2 ISDN variant with CallPriorityMode set to 1.
MLPP default service domain string. If the device receives a
non MLPP ISDN incoming call (without a Precedence IE), it
uses the parameter (if different than "FFFFFF") as a Service
domain in the SIP Resource-Priority header in outgoing (Tel-
to-IP calls) INVITE messages. This parameter is used in
conjunction with the parameter SIPDefaultCallPriority.
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 device's using the
MLPP NI-2 ISDN variant with CallPriorityMode set to 1.

Defines the RTP DSCP for MLPP Routine precedence call
level.

parameter PremiumServiceClassMediaDiffServ or as defined
for IP Profiles per call (using the parameter IPProfile).
