Abstract
A system (10) includes a packet-switched network (12). A plurality of telephones (21-26) are each coupled to the network. A call manager server (31) is also coupled to the network, in order to interact with the telephones to implement telephony functions. Each of the telephones has the capability to act as an independent network client, by using Internet-compatible protocols to communicate directly with a resource server, without the participation or even the awareness of the call manager server. The resource server may be a local server (32) coupled directly to the network, or a remote server (66-68) coupled to the network through some other network, such as the Internet (52).
