A default SIP Firewall Rule Set for the SIP Firewall is automatically provided when Session Manager is installed. The system preserves the default Rule Sets for different Session Manager releases. You can rollback to an earlier release of an Avaya-provided Rule Set by assigning earlier Rule Set versions.
After a system upgrade, the default Rule Sets associated with Session Manager and Branch Session Manager are automatically updated with the latest versions of the Rule Sets. Rule Sets created and assigned by customers remain unaffected after a system upgrade.
Note:
The installation software will only upgrade automatically to the new default rule set if the Session Manager or Branch Session Manager currently has a default rule set assigned. The default rule set s not upgraded when a customer-modified rule set is in place.
