Aura
®
Application Server 5300 server. For information on configuring the MLPP service, see
Avaya Aura
®
Application Server 5300 Using the Provisioning Client (NN42040-112).
To enable MLPP, DOD_ENABLE must be configured as YES in the device configuration file.
Precedence
Precedence enables an IP Deskphone user to specify the precedence level of each call that
is placed. During call processing, this precedence level is used to assure preferential call
completion of higher precedence calls within the same MLPP service domain, even if that
means preempting lower precedence calls.
The precedence levels are:
• Routine
• Priority
• Immediate
• Flash
• Flash-Override
• Flash-Override-Override
• Emergency
.A user can initiate a call only with a precedence level equal to or below the authorized
precedence level that has been configured for that user. All calls automatically default to
Routine, unless a higher precedence is chosen.
Once the precedence level for a call has been set, the precedence level for that call cannot be
changed.
Precedence calls cannot be placed to clients that are using SIP software earlier than SIP
3.1.
Precedence level for a call is set either at the IP Deskphone used by the user or through the
World Wide Numbering Plan at the Local Session Controller (LSC) Assured Real-Time
Services-Avaya Aura
®
Application Server 5300.
Changing call precedence:
A user must enter a user password before initiating or transferring a call with a precedence
level higher than Routine. The user is able to change the default precedence level using the
Precedence menu on the IP Deskphone: Options > Select Precedence. The menu is
available either when dialing or transferring a call.
This feature is also available when dialing from the Address Book, using Speed Dial, or using
Redial. There is no limit to the number of password retries.
The ENABLE_SERVICE_PACKAGE parameter must be configured as YES and MLPP must
be configured for the user.
