Abstract

An Internet compatible dialer pad is used to dial into an Internet server to provide services similar to those found on the Plain Old Telephone System (“POTS”). The dialer pad has an integrated modem set, an extended keypad with alphanumeric entry keys and function keys, display screen and display electronics that renders visual call progress information to the user as well as other communications indicators and related information about the current Internet connection. The dialer uses the Public Switched Telephone System (“PSTN”) and standard LAN/WAN technology to give the user entry into a plurality of Internet calling functions. An Internet database is maintained and permits the dialing party to obtain callee information by entering alphanumeric characters via the dialer. Links from the PSTN to an Internet data base are not restricted to a specific digital data protocol.

Claims

1. A method for supporting telephony services over a data network, the method comprising:

transmitting a prompt message to a telephony station of a caller for an identifier of a callee in response to detecting placement of a call to the callee;

receiving a message specifying the identifier from the telephony station of the caller in response to the prompt message; and

converting the identifier to a corresponding network address of the callee for use in establishment of the call over the data network to the callee,

wherein the telephony station includes a physical button dedicated to data network access, the physical button is configured to initiate a call via the data network to the callee without interrupting a current circuit-switched voice connection by the telephone station.

2. The method according to claim 1, wherein the identifier corresponds to one or more callees, the method further comprising:

transmitting a plurality of names of the callees to the telephony station, wherein the caller selects a particular one of the names for establishment of the call.

3. The method according to claim 1, wherein the call is a long distance call.

4. The method according to claim 1, wherein the identifier is not a valid domain name.

5. A server for supporting telephony services over a data network, comprising:

a network interface configured to transmit a prompt message to a telephony station of a caller for an identifier of a callee in response to detecting placement of a call to the callee, wherein the network interface is further configured to receive a message specifying the identifier from a telephony station of the caller in response to the prompt message; and

a processor configured to convert the corresponding identifier to a network address of the callee for use in establishment of the call over the data network to the callee,

wherein the telephony station includes a physical button dedicated to data network access, the physical button is configured to initiate a call via the data network to the callee without interrupting a current circuit-switched voice connection by the telephone station.

6. The server according to claim 5, wherein the identifier corresponds to one or more callees, and a plurality of names of the callees are transmitted to the telephony station, the caller selecting a particular one of the names for establishment of the call.

7. The server according to claim 5, wherein the call is a long distance call.

8. The server according to claim 5, wherein the identifier is not a valid domain name.

9. A system for providing directory services for calls placed over a data network, comprising:

a directory server configured to receive an identifier of a callee from a telephony station of the caller, the telephony station communicating with the data network through a circuit-switched network, wherein the telephony station includes a physical button dedicated to data network access, the physical button is configured to initiate a call over the data network to the callee without interrupting a current circuit-switched voice connection by the telephone station; and

a user database coupled to the directory server, the database storing a network address corresponding to the identifier, wherein the network address is used for establishment of the call over the data network to the callee.

10. The system according to claim 9, wherein the directory server communicates with a domain name server to obtain the network address.

11. The system according to claim 9, wherein the call is a long distance call.

12. The system according to claim 9, wherein the identifier is not a valid domain name.

13. The system according to claim 9, wherein the call is in an Internet audio format and the callee receives the call via a telephony station supporting an audio phone format, the system further comprising:

an audio conversion switch configured to convert from the Internet audio format to the audio phone format.
