CHAPTER 20 SIP Definitions
You can also configure a Call Setup rule that determines whether the device must discontinue with
the Call Setup Rules Set ID and route the call accordingly. This is done using the Exit optional
value of the 'Action Type' parameter. When used, the 'Action Value' parameter can be configured to
one of the following strings:
■ "true": Indicates that if the condition is met, the device routes the call according to the selected
routing rule. Note that if the condition is not met, the device also uses the selected routing rule,
unless the next Call Setup rule in the Set ID has an Exit option configured to "false" for an
empty condition.
■ "false": Indicates that if the condition is met, the device attempts to route the call to the next
matching routing rule (if configured). If the condition is not met, the device routes the call
according to the selected routing rule.
As the default result of a Call Setup rule is always "true", please adhere to the following guidelines
when configuring the 'Action Type' field to Exit: If, for example, you want to exit the Call Setup Rule
Set ID with "true" when LDAP query result is found and "false" when LDAP query result is not
found:
■ Incorrect -this rule will always exit with result = True:
Condition: ldap.found exists Action Type: Exit Action Value: True
■ Correct:
● Single rule:
Condition: ldap.found !exists Action Type: Exit Action Value: False
● Set of rules:
Condition: ldap.found exists Action Type: Exit Action Value: True
Condition: <leave it blank> Action Type: Exit Action Value: False
If the source and/or destination numbers are manipulated by the Call Setup rules, they
revert to their original values if the device moves to the next routing rule.
The following procedure describes how to configure Call Setup Rules through the Web interface.
You can also configure it through ini file [CallSetupRules] or CLI (configure voip > message
call-setup-rules).
