Once a rule is created, the rules can be applied on a SIP message to see how the manipulation works. The "TestMessage" can be applied to the entire table or a particular rule. The top panel is to provide the raw SIP message. On Apply the parser decodes the raw message, and encodes it. Then the rules are applied and the manipulated message is provided.
To test a message rule:
In the left navigation pane, go to SIP > Message Manipulation > Message Rule Tables >Rule Table.
Rule Table 1
Click the Test Messagetext at the top of the page.

Click OK.
