WebSphere brand IBM WebSphere Telecom Web Services Server, Version 7.1

Administering Parlay X Third Party Call over SIP/IMS

After you deploy Parlay X Third Party Call over SIP/IMS, you can use the TWSS Administration Console to change the deployment configuration properties for the Web service and related Service Platform components.

Configuration changes are read at the start of each call and do not require the system to be restarted. This will keep the call settings consistent through the lifecycle of the call. This information will be stored to the SIP application session.

TWSS Administration Console settings

This Web service implementation adds the following configurable settings to the TWSS Administration Console:
  • Services: Default values used for Parlay X Third Party Call over SIP/IMS:
    • Third Party Call Web Service: For connecting callers. The properties that can be configured include the following.
      • Media Server URI: The SIP URI address of the Media server.
      • Create pHeader: This is set if the service needs to create a security pHeader.
      • Service name: The default service name is PX21_TPC_IMS.
      • Status retain time: The amount of time in seconds to keep a call session active after the call terminates. If the value is greater than 59 seconds, the call record is written to the ThirdPartyCall database.
      • Create charging records: If present, the Parlay X Third Party Call over SIP/IMS will write these records to the call records.
      • Traffic estimate per request: An estimate on how much message traffic will be generated for each request
      • Timer duration interval: Listed in seconds. The timer manages the call records in the ThirdPartyCall database and deletes the records that have existed for longer than the status retention time. (This value depends on Status retention time having been set such that call records are written to the database.)
      • Inter Operator Identifier: This setting is used to define the home originating network identifier; for example: ibm.com
      • Outbound proxy address: This setting defines the IMS outgoing proxy when calls are initiated.
      • Outbound proxy resource specification name: Describes the needed information for traffic shaping towards the SIP proxy.
  • Common Components: Click the name of a Service Platform component–for example Fault Alarm Client or Usage Record Client–to configure it to work with this Web service implementation. If you leave the endpoint URI empty for a component, then the component is disabled.

Policies

Policy attributes are retrieved from the Service Policy Manager and are passed to the Parlay X Third Party Call over SIP/IMS Web service in the SOAP headers. If the policies are not found in the SOAP header, the Web service uses the values that are defined in the TWSS Administration Console.

For information about default policy configuration, refer to the following topic: Default service policies for Parlay X Third Party Call over SIP/IMS.
