0	ROUTINE	51 (0x33)	51 (0x33)

●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>-<subdomain>.<r-priority>

The table below shows an example of calls accepted or rejected assuming:

Domain Name = UC

Sub Domain = 000000

r-priority = 2
