[E911MLPPBehavior]
resource-prio-req
[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:
MLPP Precedence Level
0 (lowest)
2
4
6
8
9 (highest)
Version 7.2
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: The parameter is applicable only to the MLPP NI-2 ISDN
variant with CallPriorityMode set to 1.
Note: The parameter is applicable only to digital interfaces.
Defines the index of the Precedence Ringing tone in the Call
Progress Tones (CPT) file. This tone is used when the
parameter CallPriorityMode is set to 1 and a Precedence call is
received from the IP side.
The valid range is -1 to 16. The default is -1 (i.e., plays standard
ringing tone).
Note: The parameter is applicable only to analog interfaces.
Defines the E911 (or Emergency Telecommunication
Services/ETS) MLPP Preemption mode:

[0] = (Default) Standard Mode - ETS calls have the highest
priority and preempt any MLPP call.

[1] = Treat as routine mode - ETS calls are handled as
routine calls.
Note: The parameter is applicable only to analog interfaces.
Determines whether the SIP resource-priority tag is added in the
SIP Require header of the INVITE message for Tel-to-IP calls.

[0] Disable = Excludes the SIP resource-priority tag from the
SIP Require header.

[1] Enable = (Default) Adds the SIP resource-priority tag in
the SIP Require header.
Note: The parameter is applicable only to MLPP priority call
handling (i.e., only when the CallPriorityMode parameter is set
to 1).
