SAG Matching for LRT and ENUM

When this feature is enabled and a match is found, the Oracle® Enterprise Session Border Controller uses the matching SAG for routing. When there is no match for the SAG, the Oracle® Enterprise Session Border Controller processes the result as it would have if this feature had not been enabled: either matching to a session agent hostname, or performing a DNS query to resolve it.

Note that you set the state of this feature in the SIP configuration.

To configure a SAG for ENUM or LRT matching:

1. In Superuser mode, type configure terminal and press Enter.

   ORACLE# configure terminal

2. Type session-router and press Enter to access the signaling-level configuration elements.

   ORACLE(configure)# session-router
   ORACLE(session-router)#

3. Type sip-config and press Enter. The system prompt changes to let you know that you can begin configuring individual parameters.

   ORACLE(session-router)# sip-config
   ORACLE(sip-config)#

   If you are adding support for this feature to a pre-existing SIP configuration, then you must select (using the ACLI select command) that configuration to edit it.

4. enum-sag-match—Set this parameter to enabled so the Oracle® Enterprise Session Border Controller will match session agent group (SAG) names with the hostname portion in the naming authority pointer (NAPTR) from an ENUM query or LRT next-hop entry. The default value is disabled. The valid values are:

   • enabled | disabled

5. Save and activate your configuration.
