Condition Field Operands

The following table describes the condition operands.

Condition Operands

Condition Operand	Description
== !=	Tests for equivalent values. Tests for not equivalent values.
>= <=	Tests for greater than or equal to values. Tests for less than or equal to values.
> <	Tests for greater than values. Tests for less than values.
contains !contains	Tests a string containing specified text. Tests a string not containing specified text.
exists !exists	Tests whether a parameter exists. Tests whether a parameter does not exist.
suffix prefix	Tests whether a string has a particular suffix. Tests whether a string has a particular prefix.
len> len< len==	Tests whether the length of a string is greater than a specific value. Tests whether the length of a string is less than a specific value. Tests whether the length of a string is equal to a specific value.
num< num< num= num== num>= num<= num!=	Tests the numerical value (not lexicographic comparison) of the string. For more information, see Condition.
regex	Tests whether a string matches the given regular expression.
+	Concatenates string values.
insubnet !insubnet	Tests whether the host IP address (IPv4 or IPv6) in a SIP header (e.g., From or To) belongs to a specific subnet expressed in CIDR (Classless Inter-Domain Routing) notation. Tests whether the host IP address (IPv4 or IPv6) in a SIP header (e.g., From or To) does not belong to a specific subnet expressed in CIDR (Classless Inter-Domain Routing) notation.
