H.323 Endpoint-Originated Call Hold and Transfer

When calls that require the IWF originating in H.323, the Oracle® Enterprise Session Border Controller supports call hold, transfer, and conference for the H.323 call leg. The call hold and transfer feature uses signaling procedures based on the ITU-T recommendations/H.323 specification for third party initiated pause and rerouting.

You do not have to configure the Oracle® Enterprise Session Border Controller ’s call hold and transfer feature.

The following diagram shows how the Oracle® Enterprise Session Border Controller provides call hold and transfer support for IWF sessions that originate in H.323.
