Additional Options

  • The Oracle Communications Unified Session Manager can populate the top Route: header with the sescase value for ASs that require it. In such a case, the parameter is created as either call=orig or call=term. This behavior is enabled by configuring the add-sescase-to-route option in the ifc-profile.
  • When the dialog-transparency parameter in the sip-config is set to enabled and your network includes multiple ASs, you should add the dialog-transparency-support option in the ifc-profile.
  • The Oracle Communications Unified Session Manager provides an alternative, configurable option that allows the user to specify the use of route header information to determine Served User and Session Case for out-of-the-blue (OOTB) calls. This method is 3GPP-compliant. By default, the Oracle Communications Unified Session Manager uses information from the P-Served-User (PSU) header. The user configures this behavior by enabling the ignore-psu-sesscase option in the ifc-profile.
