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.

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 3 Structure for the Trigger Called New_Trigger
|
|
|
|
|
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’”.
