Rule Syntax
A call-class rule starts with the tag “rule”. All characters following the tag define the rule.
Following the rule are specifiers that define the location in the integration or display string of the
call party information.
For example, to describe the integration string:
[A1500*300#]
the rule might read:
rule A1\d(0-10)\*\d(0-10)*#
dst_number
1
src_number 2
reason no-answer
This means that when the regular expression is satisfied, the first digits string is the destination
number, the second digit string is the source number, and the reason code is 'no-answer'.
In order to describe the display:
[a= JOE 123 to BILL 456 b]
the rule might read:
rule .= \w*\s\d* to \w*\s\d*\s*~*
src_number
1
src_name 1
dst_number 2
dst_name 2
reason 1
origin internal
This means that when the regular expression is satisfied, the first digits string is the source number,
the second digits string is the destination number, the first word string is the source name, the
second word string is the destination name, and the reason code is at the end. The origin of the call
is “internal”.
