The invention claimed is:1. A method for seamlessly providing a carrier-independent peer-to-peer VoIP call, the method comprising:receiving an existing carrier-issued telephone number to be called;determining whether the existing carrier-issued telephone number corresponds to a registered telephone number stored in a carrier-independent database;based on the existing carrier-issued telephone number corresponding to the registered telephone number in the carrier-independent database:placing a call via a carrier-independent peer-to-peer connection using a first address associated with the registered telephone number, wherein the first address is a dynamic address;determining a second address for the registered telephone number during the call based on the dynamic address changing from the first address to the second address during the call;continuing the call, while keeping the call active, using the second address based on the dynamic address changing from the first address to the second address during the call; andbased on a quality of the carrier-independent peer-to-peer connection not being acceptable during the call based on a user-specific set of specifications, automatically switching the call from the carrier-independent peer-to-peer connection to a standard route, wherein the user-specific set of specifications includes a sine-wave audio echo analysis and a live MOS score; andbased on the existing carrier-issued telephone number not corresponding to the registered telephone number in the carrier-independent database, placing the call via the standard route.2. The method of claim 1, further comprising monitoring the carrier-independent peer-to-peer connection to determine if a user specification is acceptable.3. The method of claim 2 wherein the user specification comprises quality for the carrier-independent peer-to-peer connection.4. The method of claim 2 wherein the user specification comprises availability of the carrier-independent service.5. The method of claim 1 wherein the standard route comprises a PSTN connection.6. The method of claim 1 wherein the standard route comprises a third-party VoIP connection.7. The method of claim 1 further comprising registering the existing carrier-issued telephone number for carrier-independent VoIP calling service.8. The method of claim 1 further comprising performing a verification process on the existing carrier-issued telephone number.9. The method of claim 8 wherein the verification process comprises requesting a DTMF sequence from a device associated with the existing carrier-issued telephone number.10. The method of claim 8 wherein the verification process comprises a re-verification of the registered telephone number.11. The method of claim 1 wherein determining if the telephone number comprises a registered telephone number comprises using the existing carrier-issued telephone number as a lookup key in the carrier-independent database.12. The method of claim 1 wherein the step of automatically falling back to place the call via the standard route occurs during the call.13. The method of claim 1 further comprising rerouting the call to a current dynamic address for the registered telephone number during the call.14. The method of claim 1 wherein the step of monitoring occurs in real-time.15. The method of claim 1, wherein an existing communication identifier of a contactor using a first carrier is resolved to a hostname or address, the contactor contacting a recipient using a second carrier for free over IP.16. A system for seamlessly providing a carrier-independent peer-to-peer VoIP call, the system comprising:a carrier-independent database configured to store registered telephone numbers and corresponding addresses;a routing instruction module configured to determine if an existing carrier-issued telephone number being called is a registered telephone number stored in the carrier-independent database, and configured to provide a corresponding first address if the existing carrier-issued telephone number is registered in the carrier-independent database, wherein the first address is a dynamic address;a dynamic address engine configured to determine a second address associated with the registered telephone number and provide the second address to the carrier-independent database during the call when the dynamic address changes from the first address to the second address during the call;a logic configured to continue the call, while keeping the call active, using the second address when the dynamic address changes from the first address to the second address during the call;a call routing module configured to establish the call via a peer-to-peer connection over a carrier-independent network if the existing carrier-issued telephone number is registered in the carrier-independent database, and configured to establish the call via a standard route if the existing carrier-issued telephone number is not registered in the carrier-independent database; anda fallback module configured to automatically switch the call from the peer-to-peer connection over the carrier-independent network to the standard connection if the peer-to-peer connection over the carrier-independent network does not meet a quality during the call based on a user-specific set of specifications, wherein the user-specific set of specifications includes a sine-wave audio echo analysis and a live MOS score.17. The system of claim 16 further comprising a verification module configured to perform a verification process on a telephone number being registered.18. The system of claim 16, further comprising a system monitoring module configured to monitor the peer-to-peer connection to determine if a user specification is acceptable.19. The system of claim 18 wherein the system monitoring module is configured to determine quality and availability of the peer-to-peer connection.20. The system of claim 16 further comprising an update module configured to provide an updated copy of the carrier-independent database to coupled nodes.21. The system of claim 16, wherein an existing communication identifier of a contactor using a first carrier is resolved to a hostname or address, the contactor contacting a recipient using a second carrier for free over IP.22. A method for seamlessly providing a carrier-independent peer-to-peer VoIP call, the method comprising:receiving an existing carrier-issued telephone number to be called;determining whether the existing carrier-issued telephone number corresponds to a registered telephone number stored in a carrier-independent database;returning a status based on the existing carrier-issued telephone number corresponding to the registered telephone number stored in the carrier-independent database, the status triggering a call via a peer-to-peer connection using a first address associated with the registered telephone number based on the existing carrier-issued telephone number corresponding to the registered telephone number stored in the carrier-independent database, wherein the first address is a dynamic address;determining a second address for the registered telephone number during the call based on the dynamic address changing from the first address to the second address during the call;continuing the call, while keeping the call active, using the second address when the dynamic address changes from the first address to the second address during the call;based on a quality of the peer-to-peer connection not being acceptable during the call based on a user-specific set of specifications, automatically switching the call from the peer-to-peer connection to a standard route, wherein the user-specific set of specifications includes a sine-wave audio echo analysis and a live MOS score; andtriggering a call via the standard route based on the existing carrier-issued telephone number not corresponding to the registered telephone number stored in the carrier-independent database.23. The method of claim 10, further comprising monitoring the peer-to-peer connection to determine if a user specification is acceptable.24. The method of claim 10, wherein an existing communication identifier of a contactor using a first carrier is resolved to a hostname or address, the contactor contacting a recipient using a second carrier for free over IP.
