Version 6.0
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
incoming and outgoing MLPP calls with the Resource-Priority
header.
The valid range is 0 to 63. The default value is 50.
Defines the duration (in seconds) in which the device plays a
preemption tone to 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.
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 the MLPP NI-2
ISDN variant with CallPriorityMode set to 1.
Defines the MLPP network identifier (i.e., International prefix or
Telephone Country Code/TCC) for IP-to-ISDN calls, according
to the UCR 2008 and ITU Q.955 specifications.
The valid range is 1 to 999. The default is 1 (i.e., USA).
The MLPP network identifier is sent in the Facility IE of the
ISDN Setup message. For example:

MLPPNetworkIdentifier set to default (i.e., USA, 1):
PlaceCall- MLPPNetworkID:0100
MlppServiceDomain:123abc, MlppPrecLevel:5
Fac(1c): 91 a1 15 02 01 05 02 01 19 30 0d 0a 01 05 0a 01
01 04 05 01 00 12 3a bc

MLPPNetworkIdentifier set to 490:
PlaceCall- MLPPNetworkID:9004
MlppServiceDomain:123abc, MlppPrecLevel:5
Fac(1c): 91 a1 15 02 01 0a 02 01 19 30 0d 0a 01 05 0a 01
01 04 05 90 04 12 3a bc
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
357
