Abstract

The present invention includes a method or Internet phone for automatically dialing up a phone call connection across an Internet connection. Initially the caller manually dials a recipient'"'"'s telephone number, and once the telephone call connection is made, the caller party'"'"'s Internet phone automatically starts a dialing routine which notifies the recipient party'"'"'s Internet phone that a phone call connection over an Internet connection is desired. The dialing may be a differential ringing sequence or a single ringing interval. Upon the dialing routine being detected by the recipient party'"'"'s Internet phone, the parties end the telephone connection and proceed to make separate connections to the Internet, including a connection to a Lightweight Directory Access Protocol (LDAP). The caller party and recipient party Internet phones submit their respective Internet protocol address and telephone numbers. The caller party additionally submits the recipient Internet phone'"'"'s telephone number. Then the Internet connection for the intended phone call is automatically completed. Alternatively, the differential dialing routine can be performed by a knocking server on the Internet, and a directory server on the Internet can match callers and recipients by their respective telephone numbers. Additionally, the knocking server permits caller equipment to be without dialing capabilities as these are now at the knocking server.

Claims

1. A method for establishing a phone call over an Internet connection, said method comprising the steps of:

making an Internet connection by caller party communication equipment intending to establish a phone call connection over said Internet connection with recipient party communication equipment;

providing by said caller party communication equipment said caller party communication equipment'"'"'s Internet Protocol address and telephone number and said recipient party communication equipment'"'"'s telephone number to a directory server and knocking server on said Internet connection;

initiating, at said knocking server, a dialing routine to said recipient party communication equipment to notify said recipient party communication equipment of an intended phone call connection over said Internet connection;

making an Internet connection by said recipient party communication equipment in response to said recipient party communication equipment detecting said dialing routine by said knocking server;

providing automatically to said directory server, by said recipient party communication equipment, said recipient party communication equipment'"'"'s Internet protocol address and telephone number; and

completing automatically said Internet connection between said caller and recipient party communication equipment for said intended phone call.

2. The method according to claim 1, wherein said dialing routine comprises a differential ringing sequence detectable by said recipient party communication equipment.

3. The method according to claim 2, wherein said differential ringing sequence comprises providing a predetermined ringing and then disconnecting said telephone connection to said recipient party communication equipment for a predetermined stop interval, and then repeating automatically for a given number of times another telephone connection to said recipient party communication equipment followed by said predetermined ringing and then disconnecting said another telephone connection.

4. The method according to claim 3, wherein an interval of said predetermined ringing can be substituted by a duration to a tone detection of a ringing tone of said recipient party communication equipment, said knocking server being usable to detect said ringing tone of said recipient party communication equipment through a tone detection of a modem of said knocking server as a dynamic way to determine said interval of said predetermined ringing.

5. The method according to claim 1, wherein said directory service is a Lightweight Directory Access Protocol (LDAP).

6. The method according to claim 1, wherein said knocking server is located nearer said recipient party communication equipment than said caller party communication equipment on said Internet connection between said caller and recipient party communication equipment.

7. The method according to claim 1, wherein said knocking server is located nearer said caller party communication equipment than said recipient party communication equipment on said Internet connection between said caller and recipient party communication equipment.

8. The method according to claim 3, wherein said differential ringing sequence is based on at least one of geographic locations of each of said knocking server and recipient party communication equipment and condition of transmission paths in said Internet connection.

9. The method according to claim 8, wherein said differential ringing sequence comprises parameters based on an interval of said predetermined ringing, said predetermined stop interval, and number of times said predetermined ringing and said predetermined stop interval are repeated, said parameters for said predetermined ringing, said predetermined stop interval and said number of times being composed as a look-up table at said knocking server, said parameters being based on said geographic locations and said transmission path.

10. The method according to claim 1, wherein said caller party communication equipment comprises at least one of a gateway servicing telephone equipment, a local area network of personal computers, a stand alone personal computer, and an Internet phone.

11. The method according to claim 1, wherein said recipient party communication equipment comprises at least one of a gateway servicing telephone equipment, a local area network of personal computers, a stand alone personal computer, and an Internet phone.

12. The method according to claim 1, wherein said knocking server is configured for attempting an Internet connection with said recipient party communication equipment if a busy tone is received when said knocking server executes said notifying.
