Abstract

A system and method for providing call handling services on a data network telephony system. A portable information device, such as a PDA, associated with a user contains the user'"'"'s address and/or appointment book information. The address and/or appointment book information includes priority information comprising one or more address/appointment entries having associated priority levels. The priority information is transmitted from the portable information device across a link to a data network telephone or other voice communication device, where it is stored in a call handling database. When an incoming call request is received at the data network telephone, the call is handled according to the priority information contained in the call handling database.

12. The system of claim 7, wherein:

the request message includes a callee user identifier; and

wherein the network telephony connection server determines the telephone identifier for callee user identifier and includes the telephone identifier in the response message.

13. The system of claim 7, wherein:

the request message includes a callee user identifier; and

wherein the network telephony connection server determines the telephone identifier for the callee identified in the call user identifier and sends the response message to the callee at the telephone identifier.

14. The system of claim 1, wherein the data network telephone further determines a caller priority level by accessing the priority information, and performs a call handling operation in response to the caller priority level being less than a threshold priority level.

15. The system of claim 1, wherein the priority information is stored in a call handling database.

16. The system of claim 1, wherein the priority information includes an address book entry having a priority level specification.

17. The system of claim 1, wherein the priority information includes an appointment book entry having a priority level specification.

18. The system of claim 1, wherein the portable information device is a smart card.

19. The system of claim 1, wherein the portable information device is a personal computer.

20. A voice communication device comprising:

an interface to a data network,

a plurality of telephony functions operable to communicate a voice signal as voice-over-data packets on a voice-over-data channel, the voice-over-data channel being one of a plurality of data communications channels supported by the data network, the telephony functions operable to convert voice-over-data packets communicated on the voice-over-data channel to voice signals;
