The RMX uses the information in the SIP Message header to match the call to a
Precedence Domain and a Precedence Level. Table 23-9 summarizes of the default values.
Table 23-9 Precedence Domain and Resource Priority - DSCP Default Values
Resource
Precedence Level
Priority
9 FLASH-OVERRIDE-OVERRIDE
8 FLASH-OVERRIDE
6 FLASH
4 IMMEDIATE
2 PRIORITY
0 ROUTINE
NONE
SIP Dial in participants, both defined and undefined, do not inherit Precedence or
Domain characteristics from the Participant's Address Book. (Additional fields, added to
the Participant's Properties - Advanced and Address Book - Advanced dialog boxes are used
to enter and modify Precedence or Domain characteristics for SIP Dial-out participants.)
For backward compatibility, calls received with a SIP Message header that contains no
Precedence Domain and the Resource Priority information, are assigned ROUTINE
priority in the first defined Precedence Domain.
Incoming calls are accepted or rejected depending on the:
— Value of the REJECT_INCORRECT_PRECEDENCE_DOMAIN_NAME System
Flag.
— Match or mismatch of the Precedence Domains, set in the RMX and contained in the
incoming SIP Message r-value.
• The r-value is of the following format:
r-value = <domain name>
Table 23-10 shows an example of calls accepted or rejected assuming:
— Domain Name = UC
— Sub Domain = 000000
— r-priority = 2
No Resource Priority header for backward compatibility
