Aggregate Session Constraints for SIP

You can set a full suite of session constraints and then apply them to a SIP interface. The session constraints configuration contains many of the same parameters as the session agent, so you can configure a group of constraints and then apply them to a SIP interface/

The SIP interface configuration’s constraint-name parameter invokes the session constraint configuration you want to apply. Using the constraints you have set up, the Oracle® Enterprise Session Border Controller checks and limits traffic according to those settings for the SIP interface. Of course, if you do not set up the session constraints or you do not apply them in the SIP interface, then that SIP interface will be unconstrained. If you apply a single session-constraint element to multiple SIP interfaces, each SIP interface will maintain its own copy of the session-constraint.

SIP interfaces now have two states: “In Service” and “Constraints Exceeded.” When any one of the constraints is exceeded, the status of the SIP interface changes to Constraints Exceeded and remains in that state until the time-to-resume period ends. The session constraint timers that apply to the SIP interface are the time-to-resume, burst window, and sustain window.
