Feature Interaction with MLPP
Do Not Disturb Incoming call with a Routine precedence level is
rejected when Do Not Disturb is enabled on the IP
Deskphone. Incoming call with a precedence level
higher than Routine is presented even when Do Not
Disturb is enabled on the IP
Deskphone.
Multiuser When MLPP is enabled, only one user can be logged
on to the IP Deskphone.
If an MLPP user is logged on to the IP Deskphone, other
user logons are blocked.
If a non-MLPP user is logged on and a MLPP user
attempts to log on, then when the IP Deskphone detects
the new user is an MLPP user, the MLPP user is
automatically logged off. The MLPP user cannot log on
until the other user is logged off.
Speakerphone Available only for 911 calls when the Speakerphone
Exclusive to 911 Emergency feature is enabled.
DSCP and MLPP:
The DSCP feature enables the IP Deskphone to classify outgoing traffic by marking each
outgoing packet with the proper DSCP value. The User signaling packet and OA&M
management packet are marked according to preconfigured DSCP parameters in the device
configuration file. When the MLPP feature is enabled, the media packet is marked to a DSCP
value converted from the precedence level of each call.
MLPP configuration
MLPP is enabled through a service package on the ARTS-AS server.
To enable MLPP on the IP Deskphone, DOD_ENABLE must be configured as YES in the
device configuration file
