Set this parameter to configure the child realm or its parent for the Address-Realm in the Globally-Unique-Address AVL in DIAMETER UDR messages that the Oracle Communications Session Border Controller sends to the policy server.
  • Default: realm-in
  • Values:
    • realm-in—This setting means that the Oracle Communications Session Border Controller will use the same realm on which the REGISTRATION request arrived.
    • sip-interface—This setting means that the Oracle Communications Session Border Controller will use the realm associated with the SIP interface on which the REGISTRATION request arrived.
    • diam-address-realm - For the e2 interface, this value enables configurable Address-Realm AVPs. This setting points the Oracle Communications Session Border Controller to the associated realm from which it will learn Address-Realm AVP information.
user-name-mode
Determines how the User-Name AVP is constructed. Used primarily with e2 based CLF functionality.
  • Default: none
  • Values:
    • none—Oracle Communications Session Border Controller does not include the User-Name AVP in any UDRs
    • endpoint-ip—IP address of the registering endpoint is sent as the payload for the User-Name AVP
    • public-id—SIP-URI portion of the TO header from the register message is sent as the payload for the User-Name AVP
    • auth-user—Username attribute of the Authorization header from the register is sent as the payload for the User-Name AVP; if there is no authorization header, the Oracle Communications Session Border Controller will not consult the CLF and will forward the registration message.
domain-name-suffix

  • Default: .com
gate-spec-mask
With this parameter, you can configure the Oracle Communications Session Border Controller to use a mask comprised entirely of zeros (0). The default value is 255. This parameter sets the value to use for the COPs pkt-mm-3 interface.

  • Default: 255
  • Values: Min: 0 / Max: 255
allow-srv-proxy
Enable this parameter if you want to include the proxy bit in the header. The presense of the proxy bit allows the Oracle Communications Session Border Controller to tell the external policy server whether it wants the main server to handle the Diameter message, or if it is okay to proxy it to another server on the network (disabled)
  • Default: enabled
  • Values: enabled | disabled
wildcard-trans-protocol
Set this parameter from enabled if you want to use transport protocol wildcarding for Rx/Rq Flow-Description AVP (507) generation. Enabled sends a flow description of “ip”. Set this parameter to disabled if you want to use the specific media stream transport protocol.
  • Default: disabled
  • Values: enabled | disabled
watchdog-ka-timer
