A single-node network is suitable for an enterprise with no more than 20,000 users that does not have branches or has branches that do not require local regeneration. In such a network, the unified gateway and a variety of service servers are all deployed at the enterprise's equipment room, and all terminal users register with the unified gateway. If the enterprise has small-sized branches, IADs can be deployed at branches and function as proxies for user registration to the unified gateway, or IP phones can be deployed at branches and register with the unified gateway.
Network Scheme
Figure 1 shows a typical single-node network scheme.
