The VisionAIR work plan is split in several work packages, of which WP4 deals with the services integration and lab tests. This deliverable D5 is one of the deliverables within WP4. Although the title of this document only refers to telephony services, this deliverable also reports on the lab tests and integration work done for the videoconferencing services that are deployed as part of the VisionAIR platform. The reason for this is that both sets of services rely on the same underlying technology for transferring real-time human intercommunication content (voice, video and shared information) over IP-based networks.
During the definition of the VisionAIR platform, it was decided that the H.323 protocol suite would form the main technology for delivering VoIP telephony and IP videoconferencing services in VisionAIR. The justification for this was that at that time the RG had already been successfully tested for H.323 support. The Session Initiation Protocol (SIP) would be examined only marginally during WP4 in order to assess how it could be adopted in a future version of the VisionAIR platform.
The lab test and integration effort has been split into various tasks, each with a low, medium or high priority. The basic components and functionality (like the H.323 gatekeeper and authentication) received the highest priority, whereas the more experimental and enhanced features (e.g. SIP support) received a lower priority.
