IWF Call Forwarding

This section describes the Oracle® Enterprise Session Border Controller ’s IWF Call Forwarding feature, which is supported for calls initiated in SIP that require interworking to H.323.

Prior to the implementation of this feature, the Oracle® Enterprise Session Border Controller did not forward calls when the remote H.323 endpoint sent a Facility message with Call deflection as the reason and an alternate address for forwarding. Instead, it would either:

• Fail to release the initial call and initiate the forwarded call
• Drop the entire call when the remote endpoint for the call tore down the session
