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

1-3. -3. (canceled)

4. A telephony station for supporting telephony services, comprising:

a physical keypad for providing Dual Tone Multifrequency (DTMF) dialing to establish a switched voice call;

a physical button, separate from the keypad, for initiating a packet-switched voice call;

an alphanumeric keyboard for inputting a callee identifier with an alphabetic character corresponding to the packet-switched voice call; and

a display coupled to the alphanumeric keyboard and configured to display the callee identifier.

5. A station according to claim 4, further comprising:

a first jack configured to connect to a circuit-switched telephony network to support the switched voice call; and

a second jack configured to connect to the circuit-switched telephony network to support the packet-switched voice call.

6. A station according to claim 4, wherein the packet-switched voice call is a long distance call.

7. A station according to claim 4, wherein the callee identifier is not a valid domain name.

8. A station according to claim 4, wherein the physical key pad comprises numeric keys corresponding to the DTMF dialing.

9. A station according to claim 4, wherein the physical key pad comprises alphanumeric keys, and at least one key corresponds to the DTMF dialing.

10. A station according to claim 4, wherein the display shows information regarding a current callee.

11. A station according to claim 4, wherein the display shows a list of available callees.

12. A station according to claim 4, wherein the display shows a network address of an available callee.

13. A station according to claim 4, further comprising:

a communication interface configured to communicate with a computer to exchange data.

14. A method for placing a call over a data network, comprising:

dialing, via a physical keypad, Dual Tone Multifrequency (DTMF) digits to establish a switched voice call over a first jack;

concurrently initiating, via a physical button that is separate from the keypad, a packet-switched voice call over a second jack; and

inputting a callee identifier for termination of the packet-switched voice call.

15. A station according to claim 14, wherein the first jack connects to a circuit-switched telephony network to support the switched voice call, and the second jack connects to the circuit-switched telephony network to support the packet-switched voice call.

16. A station according to claim 14, wherein the packet-switched voice call is a long distance call.

17. A station according to claim 14, wherein the callee identifier is not a valid domain name.

18. A station according to claim 14, wherein the physical key pad comprises numeric keys corresponding to the DTMF dialing.

19. A station according to claim 14, wherein the physical key pad comprises alphanumeric keys, and at least one key corresponds to the DTMF dialing.

20. A station according to claim 14, further comprising:

displaying information regarding of a current callee.

21. A station according to claim 14, further comprising:

displaying a list of available callees.

22. A station according to claim 14, further comprising:

displaying a network address of an available callee.

27. A station according to claim 14, further comprising:

communicating with a computer to exchange data.
