The components in the above dial plan can be broken down as follows:
{|}
911
,{|}
If 911 is dialed, it will be sent without modification (will not be treated as a
precedence call). The string is not sent until the user presses send, OK, or the dial timeout
occurs.
{
9
[
0-4
]|}
The phone will strip off the leading two digits if they are 90-94.
{|`
R0
}
The ` identifies this as a meta operation string. This string will cause the
phone to include a Resource Priority Header for the “dsn” network domain with r-priority
identified by the second dialed character.

Multilevel Precedence and Preemption (MLPP) can only be implemented in a US
Department of Defense network. This service has two parts: precedence and preemption.
Precedence involves assigning a priority level to a call. Preemption involves the seizing of a
communications channel that is in use by a lower precedence level caller, in the absence of
an idle channel. Connections and resources that are in use by MLPP subscribers may be
preempted only by higher precedence calls from other MLPP subscribers.

Default Resource Priority Header (RPH) assignment;
defines a list of RPH namespaces as defined in RFC
4412.
Include a
domain. All network domain definitions (50 max.) are
enclosed within the
tags.
Each network domain element contains up to 10
priority entries that specify a priority level for a dialed
digit, and a character string that is displayed on the
phone for the priority call.
netname is the network domain name, 10
characters max.
priority is the r-priority level, 15 characters max.
index identifies the priority entry, and corresponds
to a dialed digit. Allowable values are 0 – 9.
name is the displayed text, 15 characters max.
