This invention provides a telephone-data network access system that permits voice communication device users to access a data network such as the Internet. A telephone-data network access device receives commands from callers and executes the commands on the data network such as send e-mail, search the data network, log on to pages supported by other parties on the data network, etc. A caller profile saves preferences of a caller for interacting with the data network. The telephone-data network access device may supply primitive commands for the caller to use individually or to construct complex command macros so that by a single command, more complex functions may be performed using the data network. By the above described techniques, callers who do not have access to devices such as a personal computer may access the data network and take advantage of the rich resources available through the data network.
