Multilevel Precedence And Preemption (Mlpp) - Polycom realpresence group series Administrator's Manual

2 Select the Default Precedence to use for outbound calls.
This setting accepts one of the defined precedence levels from the configured default domain. The
setting defaults to ROUTINE, which is the lowest precedence level defined in the default network
domain uc.
Although uc and dsn are preconfigured on the system, you can edit their settings or create other network
domains.
To define MLPP network domains:
1 To edit a domain, click
2 If needed, edit the Network Domain Name or change the Allow Incoming Calls setting. Disabling
the Allow Incoming Calls setting causes the system to reject any calls from this network domain.
3 Select a Precedence Level.
You can define a total of 10 precedence levels.
4 Configure these settings.
Setting Description
Precedence Level The name associated with the precedence level.
You can click Add Precedence Level to create a level and you can click
level.
Dial Digit A single numeric field (0-9) that represents the dialing digit used to indicate the requested
call precedence.
The precedence dial string is indicated by a leading '9' followed by the Dial Digit, followed by
the 7- or 10-digit number.
Resource Priority Represents the value in the SIP Resource Priority Header used to signal the precedence
Header level. This field accepts a single UTF-8 character.
Audio DSCP Indicates the DSCP value used for audio RTP/SRTP packets sent in calls using this
precedence level. The field accepts an integer value range from 0-63.
Video DSCP Indicates the DSCP value used for video RTP/SRTP packets sent in calls using this
precedence level. The field accepts an integer value range from 0-63.

Multilevel Precedence and Preemption (MLPP)

Multilevel Precedence and Preemption (MLPP) provides call prioritization over network resources and
far-end system access. Authorized users place precedence calls to elevate the priority of the call through
the AS-SIP network. Systems already in a call can be preempted by an incoming call with a higher priority.
In addition, precedence call signaling and media packets are marked with DSCP values associated with the
precedence level to ensure network QoS commensurate with the call precedence level.
RealPresence Group systems provide support for placing precedence calls through the use of precedence
prefix codes in the dial string. Calls can be placed at any of the precedence levels defined within the network
domain configured as the default domain for outbound calls. The default network domains uc and dsn
define five precedence levels: Routine, Priority, Immediate, Flash, or Flash Override. The system signals
