Abstract

A method and device that interrogates the availability of a called party before placing a communication from the calling party to the called party. A callback may be initiated so that both communications are completed simultaneously. The routing of communication may take place through any one of a number of different networks and at another time of the day, even if the caller does not otherwise have access to those networks.

Claims

1. A method for communication between two access devices via one or more networks, comprising the steps:

receiving a transmission in a first format through a first communication network from a first access device of a calling party, the transmission comprising a signaling message for one of establishing and transmitting voice communication for a phone call in one of a digital telephone network, an analog telephone network, and a cellular network from the calling party to a called party;

performing a first conversion converting the transmission from the first format to a second format, the second format being Internet protocol (IP);

sending the converted transmission through a second communication network, the second communication network being a data network, for reception by a second access device of the called party,

performing a second conversion further converting the converted transmission from the second format to a further format suitable for the second access device,

wherein each respective one of the first access device and the second access device comprises one of a telephone, a pager, a cellular phone, a laptop, a facsimile machine, and a multimedia workstation and said further format comprises said first format or another telecommunication protocol, and

optimizing routing of a multimedia communication between access devices, the optimizing including;

determining, by a control node, a quality of each IP network of a plurality of IP networks connected to the control node;

creating, by the control node, a quality matrix including the determined quality for the each IP network;

setting up, by the control node, a media session between an originating access device and a receiving access device across a plurality of communications networks having different communications protocols including Internet protocol (IP); and

upon successful setup of the media session, routing by the control node the multimedia communication between the originating and receiving access devices along a select path through at least a portion of one of the IP networks based on the quality matrix.

2. The method of claim 1, wherein the transmission is sent from the first access device serially to a first central node, the data network, a second central node, and the second access device.

3. The method of claim 1, wherein the first communication network is one of an analog telephone network, a digital telephone network, a cellular network, WiFi network, WiMax network, LTE network, and satellite system.

4. The method of claim 1, wherein a calling party is connected to the first access device for transmitting and receiving voice communication for a phone call and a called party is connected to the second access device for transmitting and receiving the voice communication for the phone call.

5. The method of claim 1, further comprising the step of selecting a route for the transmission based on at least one criteria defined by user preference.

6. The method of claim 5, wherein the at least one criteria comprises a specified level of transmission quality.

7. The method of claim 5, wherein the at least one criteria comprises credit availability of a calling party.

8. The method of claim 5, wherein the at least one criteria comprises cost of routing.

9. The method of claim 1, wherein the transmission comprises execution of at least a part of a call setup procedure.

10. The method of claim 1, further comprising the step of storing at least one of subscriber information, rate schedules, and call details.

11. The method of claim 1, further comprising a second conversion from the second format to a further format suitable for the second access device.

12. The method of claim 11, wherein the further format comprises said first format or another telecommunications protocol.

25. The method of claim 1, wherein the transmission consists of a signaling message including an identification number of the called party.

26. The method of claim 1, wherein the transmission further comprises a voice component, wherein the voice component of the transmission is converted into a format suitable for the data network or another data network, sent using the data network or the another data network, and reconverted to voice transmission prior to reaching the called party.

29. The method of claim 1, wherein the transmission consists of a signaling message including an identification number of the calling party.

30. The method of claim 1, wherein the transmission consists of a signaling message including identification numbers of both the calling party and the called party.

13. A system for transmitting communications between two access devices, the system comprising:

a first node accessible by a first access device of a calling party using a first communication network,

said first node being a telecommunication node configured to receive a transmission in a first format from the calling party through the first network, the transmission comprising a signaling message for one of establishing and transmitting voice communication for a phone call from the calling party to a called party; and

a first converter converting the transmission from the first format to a second format, the second format being an Internet protocol (IP),

said first node being further configured to transmit the converted transmission through a second communication network to second node capable of connecting to a called access device of the called party, the second node having a second converter converting the transmission from the second format to a further format suitable for the second access device, said further format comprising said first format or another telecommunication protocol, and

a control node for optimizing routing of a multimedia communication between access devices, the control node configured to determine a quality of each IP network of a plurality of IP networks connected to the control node, create a quality matrix including the determined quality for the each IP network, set up a media session between an originating access device and a receiving access device across a plurality of communications networks having different communications protocols including Internet protocol (IP), and upon successful setup of the media session, route the multimedia communication between the originating and receiving access devices along a select path through at least a portion of one of the IP networks based on the quality matrix.

14. The system of claim 13, said first node further comprising means for receiving voice communications initiated by the called party from the data network and converting the received voice communications from said first format to said second format.

15. The system of claim 13, said first node further comprising a server for connecting the first node to the data network and a telephone server for connecting the node to the one of a digital telephone network, an analog telephone network, and a cellular network.

16. The system of claim 15, wherein the telephone server comprises a Public Switched Telephone Network Interface.
