About Triggers

A trigger is a set of conditions that can be used to dictate routing and normalization logic. It is automatically executed in response to a certain event (or condition case). Conditions can have multiple cases.

Note the structure:

  • A trigger is made up of one or more rules.

  • A rule is made up of one or more conditions.

  • A condition is made up of one or more cases.

For information on available triggers, see Available Trigger Conditions and Cases.

Example of a Trigger

You might have a trigger called New_Trigger. New_Trigger might have three rules, numbered 1, 2, and 3. Each rule has at least one condition and each condition has a case.

Table 1. Structure for the Trigger Called New_Trigger

Trigger Rules

Logic

Condition

1

Inbound Network is exactly ‘100’

AND

Local IP Address is exactly ‘100.10.10.101’

AND

SIP Message request

2

OR

Time Of Day is exactly ‘200’

AND

Mid-Dialog

AND

SIP Method UPDATE

3

OR

Outbound Network is exactly ‘300’

AND

Transport Protocol tcp

In the previous table, the trigger is called New_Trigger. New_Trigger has three rules. Because of the “OR” logic, only one of the three rules has to be true before the trigger is launched.

Rule 1 has three conditions:

  • Inbound Network is exactly ‘100’

  • Local IP Address is exactly ‘100.10.10.101’

  • SIP Message request

Because of the “AND” logic, all three conditions must be true before the rule is true.

In the condition “Inbound Network is exactly ‘100’”, the condition is “Inbound Network” and the case is “is exactly ‘100’”.

Available Trigger Conditions and Cases

The table lists the available trigger conditions and cases.
