Abstract

A system and method for associating notes to a call with a portable information device, such as a personal digital assistant. In one embodiment, notes taken during a call are associated with information about the call, such as parties to the call, the date and time, and the subject matter of the call. Notes taken may include user input or PID data communicated across a telephony network, for example. In one embodiment, a portable information device links to a data network telephone to initiate a phone call. Information about the phone call is stored with notes taken to allow for later retrieval.

at least a first and second user communicate on the voice-over-data channel and a graphical data channel, each user identified by a user identifier that includes a unique sequence of alpha numeric elements.

3. The system of claim 2 wherein each data network telephone includes a device identifier that corresponds to the user identifier.

4. The system of claim 3 wherein the device identifiers include Internet Protocol (IP) addresses.

5. The system of claim 3 wherein the user identifiers include Session Initiation Protocol (SIP) addresses.

6. The system of claim 3 wherein the user identifiers include E.164 telephone numbers.

7. The system of claim 1 further comprising:

a network telephony user database connected to the data network to store a user identifier and a telephone identifier corresponding to the user identifier for each of a plurality of users, wherein;

the user identifier includes a first sequence of alphanumeric elements that identify a corresponding user;

the telephone identifier includes a second sequence of alphanumeric elements that identifies a corresponding data network telephone; and

a network telephony connection server operable to receive a request message from the first data network telephone to initiate the voice over data channel and the PID data with the second data network telephone, and to send a response message in response to the request message.

8. The system of claim 7, wherein the response and request messages are communicated by the network telephony connection server in accordance with the Session Initiation Protocol (SIP).

9. The system of claim 7, wherein the response and request messages are communicated by the network telephony connection server in accordance with the H.323 Protocol.

10. The system of claim 7 wherein the response and request messages are communicated by the network telephony connection server in accordance with the MEGACO protocol.

11. The system of claim 7 wherein the response and request messages are communicated by the network telephony connection server in accordance with the MGCP protocol.

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 the 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 callee user identifier and sends the response message to the callee at the telephone identifier.
