Creation

For your Oracle Communications Session Border Controller to create session agents dynamically, you must enable the create-dynamic-sa in the global SIP configuration. This parameter defaults to disabled, meaning that no dynamic session agents will be created.

When you set the parameter to enabled, the Oracle Communications Session Border Controller decides whether or not to create dynamic session agents in the following ways. The system will create up to five (5) dynamic session agents.

• If the Service Route is an IP address, the Oracle Communications Session Border Controller attempts to find an exact match for that IP address against pre-existing session agents. If no exact match appears, the system will not create dynamic session agents.
• If the Service Route is an FQDN and matches an existing session agent, the Oracle Communications Session Border Controller assigns the remote S-CSCF to that session agent.

  Service Routes with FQDNs might not match any session agents. However, the Service Route’s FQDN can match the DNS suffix of a wildcard session agent. When this wildcard matching occurs, the Oracle Communications Session Border Controller creates a new dynamic session agent with the original wildcard session agent as its parent. The new dynamic session agent inherits all configuration properties of the parent session agent.

• If the Service Route is neither an IP address nor an FQDN and the system is unable to match any statically defined or wildcard session agents, then the Service Route is not associated with any session agents.
