AARNet is piloting an ISDN video conferencing gateway service in partnership with Flinders University. The pilot service will provide IP and ISDN-based video conferencing. In the first phase, the service will be implemented across Flinders University. A billing model will be developed based on usage. In the second phase, the service will be offered to other Australian research and education institutions. The goal is to eventually enable institutions to save costs by moving all ISDN conferencing to the centralized production service.
