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>
The table below shows an example of calls accepted or rejected assuming:
 Domain Name = UC
 Sub Domain = 000000
 r-priority = 2
