Use the Message Manipulation window to assign SIP message manipulation (SMM) profiles (SIP adaptor profiles) that apply to a specified SIP trunk group on ingress or egress, and to specify how to execute SIP adaptor profiles if you define profiles at more than one level.The SBC supports applying SIP adaptor profiles at the SIP trunk group level as well as the global, address context, and zone levels. You have the option to define profiles at any or all of these levels. Refer to SIP Message Manipulation for more information on SMM.
If more than one profile applies to a session, you can enable "fixed order" execution of the SMM profiles. In fixed order execution, the SBC logically concatenates the rules in the applicable profiles and executes them in the following order: global, address context, zone, SIP trunk group. The collection of rules are treated as though they reside in a single profile and therefore variable values set at the beginning of the sequence are accessible to rules that follow in the sequence.
By default, fixed order execution of SMM profiles is not enabled and the rules of the SIP adaptor profile assigned to the SIP trunk group take precedence over any other configured profiles. If there is no profile assigned to the SIP trunk group, then the SBC applies the profile assigned to the zone, if a zone-level profile is present.
On the SBC main screen, go to All > Address Context > Zone > SIP Trunk Group > Signaling > Message Manipulation or
Configuration > System Provisioning > Category: Trunk Provisioning > Trunk Group > SIP Trunk Group > Signaling > Message Manipulation
The Message manipulation window opens. Using the drop-down lists, select the Address Context, Zone, and SIP Trunk Group that you want to configure.

Table 1: SIP Trunk Group - Message Manipulation Parameters
Parameter | Description |
---|---|
Input SMM Profile | Select the name of a SIP adaptor profile to use on inbound messages to this SIP trunk group. |
Output SMM Profile | Select the name of a SIP adaptor profile to use on inbound messages to this SIP trunk group. |
Include App Hdrs | Use this option to specify whether to allow the SBC to add headers in outgoing messages.
|
Smm Profile Execution | Specifies whether or not to use fixed order processing when more than one SIP adaptor profile applies to messages in sessions associated with the specified SIP trunk group. The options are:
Selecting Fixed Order also enables configuring options for each specific level (global, address context, zone, SIP trunk group) to define whether or not to execute the profiles configured at that level. Use the Addresscontext, Global, Iptg, and Zone windows below this window to enable/disable profile execution. |
