 For "Voice Over IP" and Multimedia Conferencing
The L2W-323 is a fully self-contained "standalone" gateway that translates between H.323 and H.320 protocols, converting multimedia information from circuit switch to H.323 IP packets. On the PSTN side, it supports voice-only calls as well as H.320 videoconferencing sessions. Depending on the network provisioning on the wide area, the L2W-323 enables users to exchange audio, video and data in real time at 64kbps, 128kbps, 256kbps, 384kbps and 768kbps. "Voice Over IP" gateway features include Interactive Voice Response (IVR), echo cancellation and DTMF support. The L2W-323 supports up to eight concurrent voice calls or four concurrent video calls between users on different networks. Users of a L2W-323-enabled network also benefit from full end-to-end support for T.120 sessions, provided all terminals support the standard in their collaborative applications.
Built-In Gatekeeper Provides Virtual PBX Call Control
The L2W-323 Gateway, working in conjunction with an embedded RADVision H.323 GateKeeper, provides the functionality of a multimedia Private Branch Exchange (PBX) allowing internetwork calls, Direct Inward Dialing (DID), call forward and transfer, and custom call control via IVR and DTMF signaling. Optional hardware modules perform real-time audio transcoding between G.723 to G.711, and G.728 to G.711.
