H.323 Signaling Services

The Oracle® Enterprise Session Border Controller supports H.323 signaling in a way that permits interworking between different H.323 configurations from different providers and carriers. H.323 signaling capabilities on the Oracle® Enterprise Session Border Controller include:

  • H.323 V4—Improves on previous versions of the protocol in functionality, scalability, and reliability
  • H.225 call signaling with RAS—Establishes connections between H.323 endpoints so real-time data can be exchanged
  • H.245—Establishes the type of media flow and manages that flow after it has started
  • H.245 tunneling—Encapsulates H.245 messages within H.225/Q.931 messages; when enabled and used with a firewall, one less TCP port is needed for incoming connections
  • Fast Start (and Fast Start with parallel H.245)
  • H.323 Annex E support for UDP signaling—Provides for multiplexed call signaling over UDP to increase potential call volume and enhance performance
