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 Precedence Level in Resource-Priority SIP Header
