NCID (Network Caller ID) is Caller ID (CID) distributed over a network to a variety of devices and computers. The NCID system consists of the required NCID package and optional packages. Third party addons are also available. The NCID package consists of the server, gateways, the universal client, and client output modules. The NCID server monitors either a modem, Caller ID device, or gateway for the CID data. The data is collected and sent, via TCP, to one or more connected clients. The server supports multiple gateways which can be used with or without a modem or device.
