Configuring Interworking

If you have already completed the steps outlined in this chapter’s IWF Service Enhancements section, then enabling the IWF is a simple process. This section shows you how to enable the IWF, and how to enable certain features that you can use to supplement basic IWF functionality.

An IWF configuration might appear like this in the ACLI:

iwf-config
        state                          enabled
        media-profiles
                                       PCMU
                                       telephone-event
        logging                        disabled

Configure IWF

To enable the Inter-working Function (IWF) on your Oracle Communications Session Border Controller :

1. Access the iwf-config configuration element.

   ORACLE# configure terminal
   ORACLE(configure)# session-router
   ORACLE(session-router)# iwf-config
   ORACLE(iwf-config)#

2. state—Enable this parameter if you want to translate SIP and H.323 sessions on your Oracle Communications Session Border Controller . The default value is disabled. Valid values are:

   • enabled | disabled

3. media-profiles—Enter the name of the media profiles you want to use for IWF translations. This name is either the name of an SDP codec (such as PCMU), or it can be telephone-event if you are configuring your system for DTMF support.

   If you want to use more than one media profile for SIP/H.323 translations, enter the names in quotation marks with a space between each one.

   ORACLE(iwf-config)# media-profiles "PCMU telephone-event"

4. logging—Enable this parameter if you want the Oracle Communications Session Border Controller to log SIP messages that are related to the IWF. The default value is disabled. Valid values are:

   • enabled | disabled

5. forward source call—Type enable if you want to the Oracle Communications Session Border Controller to add the h225SourceCallSignalAddress header to the egress SIP INVITE.
6. Type done to save your configuration.
