Trillium | H.323 Control
Description
The H.323 Control software product is a complete implementation of the H.323 protocol stack, which includes the H.225 Call Signaling, H.225 RAS Signaling, H.245 Control Signaling protocols and an enhanced set of H.323 specific annexes.
Trillium H.323 Control software enables telecom equipment manufacturers of soft switches, signaling gateways, signal transfer points, service control points, media gateway controllers or other products to:
- Accelerate time to market
- Reduce development costs
- Reduce project risk of internally developed H.323 Control applications
Product deliverables consist of C source software, documentation, training, a warranty and technical support.

- Full backward compatibility for H.323 version 3 and H.323 version 2.
- Provides interfaces to build the H.323 Gateway, Gatekeeper, multipoint controller and terminal applications.
- Supports the co-existence of multiple H.323 entities, such as Gatekeeper and Gateway, using the same instance of the code.
- Supports fast connect procedures.
- Supports tunneling of H.245 messages in H.225 Call Signaling PDUs.
- Supports fast connect with parallel H.245 procedures.
- Supports static and round-robin distribution of incoming calls.
- Supports the transparent Gatekeeper-routed call model.
- Supports procedures defined in H.323 Annex E for transport of H.225 Call Signaling messages over an unreliable channel.
- Supports procedures defined in Annex K for providing HTTP based service control transport channel in H.323 networks.
- Supports procedures defined in Annex L for stimulus signaling procedures between H.323 terminals and feature server entities. The H.323 API allows encapsulation of MEGACO/H.248 messages in H.225 call signaling messages.
- Supports procedures defined in Annex M.1 for tunnelling of Q.SIG messages inside H.225 messages.
- Supports procedures defined in Annex M.2 for tunnelling of Q.ISUP messages inside H.225 messages.
- Supports procedures defined in Annex M.3 for tunnelling of DSSI messages inside H.225 messages.
- Supports procedures defined in Annex J to provide security for H.323 Annex F simple endpoint types.
- Provides support for Fault-Tolerant/High-Availability (FT/HA).
- Provides the option of exposing or not exposing the RAS functionality to the endpoint/Gateway/MCU user.
- Provides the ASN.1 Encoder/Decoder PER library to support transmission and reception of all H.323 messages that use ASN.1 Encoder/Decoder PER messages.
- Provides detailed call statistics and accounting information.
- Supports procedures for error detection and recovery.
- Provides a management interface for configuration and control operations, and status and statistics retrieval. It also provides protocol state and alarm information at the management interface.
- Provides extensive run-time error checking support
- Provides extensive debugging support to ease system integration and testing.
- Provides support for function call traces and tracing of incoming and outgoing PDUs. The trace information is provided at the management interface, which can be used to support remote logging and analysis operation.
- Conforms to Trillium Advanced Portability Architecture (TAPA)
- Benefits of licensing Trillium software from Continuous Computing
