FreeSWITCH 1.8

regex operator (multiple variables and/or expressions)

You can go to great lengths with a regular expression checking a variable. I mean, you can have a regular expression so complex as to be indistinguishable from the line noise picked up by old modems. But there are cases where you want to check the relationship between two or more variables, or check multiple expressions which are not easily combined.

In these cases you use the "regex" operator to combine multiple fields and expressions into one only condition. You combine them with one only criterium:

• all: all expressions must be evaluated as true for the condition to be true (logical AND)
• any: at least one expression must be evaluated as true for the condition to be true (logical OR) ...
