Overview
SIP Adaptor Profile
The SIP adaptor profile object is the main construct for SIP Message Manipulation (SMM) functionality. Using SMM criteria and actions, you define SMM rules within a SIP adaptor profile. The SBC applies the profile to SIP messages in order to modify their headers and/or parameters. When a message comes into or out of the SBC and a SIP adaptor profile applies, the message is evaluated based on the set of criteria in the profile. If the message meets the criteria, it is modified according to actions defined in the profile. You can assign SMM profiles at the global, address context, zone, and SIP trunk group 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. The SBC supports up to 512 SIP Adaptor Profiles.
Note
Note
The number of rules in a profile is limited to 10,000 and the number of actions across profiles in a system is limited to 50,000.
Ensure the above conditions are met before LSWU.
Flexible Policy Adaptor Profile
NOTE: Flexible Policy is not supported on ERE and is intended for use with an external PSX only.
The SIP adaptor profile can also be configured to support a flexible policy mechanism to facilitate dynamic routing and policy decisions based on any SIP message information element whereby routing and policy selection criteria are provisioned by the operator. An information element can be anything in the message, such as the following examples:
- SIP header value
- Presence or absence of a header
- String in a message body
- Parameter value
- Presence or absence of a parameter
The following CLI objects are used in supporting flexible policy and routing.
The
profileTypeparameter is used to specify whether a SIP adaptor profile is used for flexible policy or message manipulation (default).The
flexiblePolicyAdapterProfilezone object is used to assign a flexible policy-specific SIP adaptor profile to a specific zone.The
flexiblePolicyAdapterProfileSIP trunk group object is used to assign a flexible policy-specific SIP adaptor profile to a specific trunk group.
For Flexible Policy and Routing feature implementation, refer to Flexible Policy and Routing Support.
For Flexible Policy and Routing best practices, refer to Configuring Dynamic Policies and Routing Using Flexible Policy and Routing Feature.

Notes
In the SMM rule above:
- Action 7 will be performed if parameter icid-generated-at matches with value someproxy.sipart.com
- Action 9 will be performed if parameter icid-generated-at matches with value abc.sipart.com or regular expression abc.*.com
- Action 1 will be performed for all the other values. This is because, "others" is a keyword used to match all other values.
Generally others is given as the last switch value. If it is not required to match the all other values, it can be ignored.
