assigned Call Setup Rules Set ID, and then routes the call according to the destination
configured for the routing rule. The device uses the routing rule to route the call, depending
on the result of the Call Setup Rules Set ID:

Rule's condition is met: The device performs the rule's action and then runs the next
rule in the Set ID until the last rule or until a rule with an Exit Action Type. If the Exit
rule is configured with a "True" Action Value, the device uses the current routing rule.
If the Exit rule is configured with a "False" Action Value, the device moves to the next
routing rule. If an Exit Action Type is not configured and the device has run all the
rules in the Set ID, the default Action Value of the Set ID is "True" (i.e., use the current
routing rule).

Rule's condition is not met: The device runs the next rule in the Set ID. When the
device reaches the end of the Set ID and no Exit was performed, the Set ID ends with
a "True" result.
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

Correct:
•
Single rule:
Condition: ldap.found !exists
•
Set of rules:
Condition: ldap.found exists
Condition: <leave it blank>
Note: 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).

To configure a Call Setup rule:
8. Open the Call Setup Rules table (Setup menu > Signaling & Media tab > SIP
Definitions folder > Call Setup Rules).
