1. If there are any conditions for the SMM Rule, add a Condition Rule.
   Some example conditions might be:
   • Only on a particular phone number

   • Only a specific header (name)
     
     In the example below, the Called Number must be 'anonymous'. This condition will be applied later in the SIP Message Rule.

     1a: Add a Condition Rule 1b: Select a Match Type Token value; this states the SIP Packet element (diversion number, IP address, etc.) for the match. Then, complete of the remainder which provides the value you desire to match.

2. Decide which type of SIP packets are to be changed. The types of SIP packets to be changed is selected when the SMM Message Rule Table is created.

   2a: Add a SIP Message Rule Table 2b: Select which SIP Messages will be examined by this Rule Table 2c: Will this SMM Table be Mandatory or Optional within the Signaling Group?

3. What SIP Packet element needs to be changed?
   • Click the name of the newly created SMM Table in the left-hand navigation tree, then add an SMM Rule entry.

   • Which type of Rule? Use the diagram below!

     Panel
     3: Add one of the Rule Types: Header, Request, Status, or Raw

4. Identify which rule section corresponds to the SIP element you want to change.

   • Example: If you wanted to change the FROM number to something other than anonymous
     From: <sip:anonymous@10.1.1.74>;tag=254b0000

   Steps to create a SMM Rule

   Panel

   5a: Select the Result Type. This setting operates exactly the same as the Translational Table optional/mandatory. 5b: Set the Action to Add, Remove, Copy, or Modify. The available options will vary based upon the type of rule you're adding. If you think about it, you can't _add a Request URI or Status Line; the SIP packet already has one, right? 5c: For a Header Rule, you'll need supply a Header Name either from the pre-progammed list or by simply typing the name of the header if it doesn't appear in the list. Request and Status Rules address only the Request and Status headers, so those rules don't require the user to pick a header. 5d: Configure the target rule setting. In the case of the example for changing any calling number of anonymous to 1000, set the User URI info to Modify and add the configuration/value you want the SIP element changed to. 5e: If you created a Condition in Step 1, add it to the Rule entry now. In this example, the SMM will only execute if the Calling Number is 'anonymous'.

6. Configure your new rule into either a Signaling Group or Call Route.
   SMM Rules can be processed either ingress or egress at the Signaling Group.
