Setting the Match Value
Note that for the SIP header rules and for the SIP element rules, the match-value parameter can now be set with these Boolean operators:
- and (for which the syntax is the ampersand &)
- or (for which the syntax is the pipe|)
However, you can only use Boolean operators in this value when you set the comparison-type parameter to pattern-rule and are evaluating stored matches. The Oracle® Enterprise Session Border Controller evaluates these Boolean expressions from left to right, and does not support any grouping mechanisms that might change the order of evaluation. For example, the Oracle® Enterprise Session Border Controller evaluates the expression A & B | C (where A=true, B=false, and C=true) as follows: A & B = false; false | true = true.
You can set the match-value for the SIP header rules or for the SIP element rules.
