Follow these steps to configure the Converged Application Server persistence options to use an RDBMS call state store:

1. From the Edit Tree of Remote Console, select Custom Resources, and then sipserver, and then SIP Server, and then Persistence.
2. Configure the Persistence attributes as follows:
   • DB Enabled: Check to enable call states to be stored in an RDBMS.
   • Default Handling: Select db or all. It is acceptable to select all because geographically-redundant replication is only performed if the Geo Site ID and Geo Remote T3 URL fields have been configured.

     For information on configuring geographical redundancy, see "Configuring Geographically-Redundant Installations".

3. Click Save, and then the shopping cart, and then Commit Changes.
