Abstract

An appliance connected to a cellular phone performs VoIP connectivity by using the cellular phone data connectivity platform. This expands the capabilities of regular cellular phones, and allows users to place and receive mobile VoIP phone calls using their older generation cellular phones.

Claims

1. An appliance device for connecting to a cellular telephone and permitting a Voice over Internet Protocol (VoIP) phone call, the device comprising:

an appliance having a connector configured to removable secure the appliance to external electrical contacts of a cellular phone, the appliance also having one or more accessible electrical contacts sized and positioned to meet with external electrical contacts of a cellular phone;

a software module contained in the appliance, the software module comprising machine readable instructions that along with the assistance of the cellular phone, is adapted to;

control the dialing functionality of the cellular phone, establish and maintain a data connection via a cellular network, and establish and complete a VoIP phone call.

2. The device according to claim 1, wherein the software module further comprises machine readable instructions for converting an analog voice signal to packet data.

3. The device according to claim 1 wherein the software module contains instructions to enable a cellular phone configured to communicate over a GSM network to communicate over a data packet network.

4. The device according to claim 3, wherein the data packet network is GPRS.

5. The device according to claim 1, further comprising an additional connector for connecting an external accessory to the appliance.

6. The device according to claim 5 wherein the external accessory is a microphone, battery charger, speaker, and/or a headset.

7. The device according to claim 1 wherein the software module further comprises machine instructions for adapting the coding and decoding of analog or digital voice signals in a CODEC to digital packet data in compliance with a VoIP protocol.

8. The device according to claim 1, wherein the software module further comprises machine readable instructions for performing connection and authentication with an Internet Telephony Service Provider (ITSP).

9. The device according to claim 1, wherein the machine readable instructions establish a VoIP call using of one the following VoIP protocols:

Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), H.323 protocol, Inter Asterisk eXchange protocol (IAX), Gateway Control Protocol (MEGACO), and Skinny Call Control Protocol (Cisco SCCP).

10. The device according to claim 1, wherein the software module further comprises machine readable instructions to support a VoIP communication using Internet Protocol Version 4 (IPv4) or Internet Protocol Version 6 (IPv6).

11. The device according to claim 1, wherein the software module contains machine readable instructions for having voice data transmitted in data packets during a VoIP call using Real-Time Transport Protocol.

12. The device according to claim 7 wherein the VoIP protocol is H.323 protocol.

13. The device according to claim 1, wherein the machine readable instructions include instructions to obtain a VoIP proxy over an Internet Protocol network.

14. The device according to claim 1, wherein the machine readable instructions also enable the cellular phone to continue to send and receive communications over a non-IP communication protocol.

15. The device according to claim 1 wherein the data connection established by the cellular phone is based on second generation (2G) mobile communications standards, third generation (3G) mobile communications standards, or fourth generation mobile communications standards (pre-4G and 4G).

16. A method for making Voice over Internet Protocol (VoIP) phone calls using a cellular telephone:

connecting an appliance to a connection of a cellular phone;

dialing a telephone number;

sending instructions from the appliance to the cellular phone to establish a data connection using the cellular phone, the data connection established carries VoIP protocol packets;

sending data packets from the appliance to the cellular phone to establish a VoIP connection using the established data connection, the VoIP connection establishing a VoIP proxy at a location in an Internet Protocol network remote from the cellular phone; and

transmitting VoIP data packets using digital encoding and decoding techniques of a VoIP protocol.

17. The method of claim 16 wherein the VoIP protocol is H.323.

18. The method of claim 16 wherein the VoIP protocol is one of the following protocols:

Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), H.323 protocol, Inter Asterisk eXchange protocol (IAX), Gateway Control Protocol (MEGACO), and Skinny Call Control Protocol (Cisco SCCP).

19. The method of claim 16 further comprising:

generating signaling instructions for VoIP communication in the appliance and broadcasting those instructions with an antennae of the cellular phone.

20. The method of claim 16 further comprising:

receiving signals at the appliance from the cellular phone representing touchtone signals of a telephone number, and

generating signals in the appliance to establish the VoIP proxy for voice communications with the telephone number identified by the received touchtone signals.

21. The method of claim 16 wherein prior to connecting the appliance to the cellular phone, the cellular phone contains instructions for sending and receiving cellular communications using the GSM protocol, CDMA protocol or TDMA protocol.

22. The method of claim 16 wherein an external microphone, battery charger, speakers and/or headsets are connected to the appliance.

23. The method of claim 16 wherein the data connection established by the cellular phone is based on second generation (2G) mobile communications standards, third generation (3G) mobile communications standards, or fourth generation mobile communications standards (pre-4G and 4G).
