Abstract

Implementations relate to selection of networks for voice call transmission. In some implementations, a method includes determining a voice call for communication between a sending device initiating the voice call and a receiving device and determining one or more first characteristics of the voice call. The method selects, based on the first characteristics, one of a phone network and a data network to use to route data of the voice call from the sending device to an intermediary server on the data network. The method causes the data of the voice call to be sent to the intermediary server over the selected network. The data of the voice call is sent from the intermediary server to the receiving device on one of the phone network and the data network chosen by the intermediary server based on one or more second characteristics of the call.

Claims

1. A method comprising:

receiving, at an intermediary server, data of a voice call for communication between a sending device that initiated the voice call and a receiving device, wherein the data of the voice call is received from the sending device over one of a phone network or a data network as selected by the sending device based on one or more first characteristics of the voice call, wherein the intermediary server is coupled to the data network and the phone network, wherein the receiving device is associated with an intermediate phone number used as an address to the intermediary server in response to the data of the voice call being received over the phone network, wherein the intermediate phone number is one of a plurality of intermediate phone numbers used as addresses to the intermediate server, each of the plurality of intermediate phone numbers corresponding to a respective user or a respective user device;

choosing, based on one or more second characteristics of the voice call, one of the phone network or the data network to use to route the data of the voice call from the intermediary server to the receiving device;

selecting a communication identity for the receiving device different than the intermediate phone number based on the chosen network between the intermediary server and the receiving device; and

causing the data of the voice call to be sent to the receiving device over the chosen network using the communication identity.

2. The method of claim 1 wherein selecting the communication identity for the receiving device includes one of:

selecting a phone number of the receiving device different than the intermediate phone number in response to choosing the phone network, or

selecting a network address of the receiving device on the data network in response to choosing the data network.

3. The method of claim 1 wherein the intermediary server is coupled to the phone network by one or more first path gateways between the intermediary server and the sending device and by one or more second path gateways between the intermediary server and the receiving device.

4. The method of claim 1 wherein the one or more second characteristics of the voice call include one or more call characteristics of the receiving device.

5. The method of claim 1 wherein the one or more second characteristics of the voice call include at least one of:

one or more network conditions of the phone network and of the data network;

or

a cost to the sending device to establish the voice call between the sending device and the receiving device.

6. The method of claim 1 wherein choosing, based on one or more second characteristics of the voice call, one of the phone network and the data network includes:

determining a phone network score for the phone network based on the one or more second characteristics; and

determining a data network score for the data network based on the one or more second characteristics,

wherein choosing one of the phone network and the data network is based on a comparison of the phone network score and the data network score.

7. The method of claim 1 wherein choosing one of the phone network or the data network is further based on obtained first user preference data that indicates one or more user preferences of a receiving user of the receiving device with respect to at least one of the one or more second characteristics.

8. The method of claim 7 wherein choosing one of the phone network or the data network is further based on obtained second user preference data that indicates one or more user preferences of a sending user of the sending device with respect to at least one of the one or more second characteristics.

9. The method of claim 7 wherein the user preferences of the receiving user indicate a permission to cause an alert at the receiving device during designated times upon receipt of the voice call from one or more designated users.

10. The method of claim 1 wherein selecting the communication identity for the receiving device includes searching data storage accessible to the intermediary server and obtaining the communication identity of the receiving device that is associated in the data storage with the intermediate phone number.

11. The method of claim 1 wherein selecting the communication identity for the receiving device includes sending a request to the sending device to obtain the communication identity of the receiving device that is associated with the intermediate phone number.

12. A system comprising:

a storage device; and

at least one processor configured to access the storage device and configured to perform operations comprising;

receiving, at an intermediary server, data of a voice call for communication between a sending device that initiated the voice call and a receiving device, wherein the data of the voice call is received from the sending device over one of a phone network or a data network as selected by the sending device based on one or more first characteristics of the voice call, wherein the intermediary server is coupled to the data network and the phone network, wherein the receiving device is associated with an intermediate phone number used as an address to the intermediary server in response to the data of the voice call being received over the phone network, wherein the intermediate phone number is one of a plurality of intermediate phone numbers used as addresses to the intermediate server, each of the plurality of intermediate phone numbers corresponding to a respective user or a respective user device;

obtaining one or more second characteristics of the voice call;

choosing, based on the second characteristics of the voice call, one of the phone network or the data network to use to route the data of the voice call from the intermediary server to the receiving device;

selecting a communication identity for the receiving device different than the intermediate phone number based on the chosen network between the intermediary server and the receiving device; and

causing the data of the voice call to be routed to the receiving device over the chosen network using the communication identity.

13. The system of claim 12 wherein the operation of selecting the communication identity for the receiving device includes one of:

selecting a phone number of the receiving device different than the intermediate phone number in response to choosing the phone network, or

selecting a network address of the receiving device on the data network in response to choosing the data network.

14. The system of claim 12 wherein the intermediary server is coupled to the phone network by one or more first path gateways between the intermediary server and the sending device and by one or more second path gateways between the intermediary server and the receiving device.

15. The system of claim 12 wherein the second characteristics of the voice call include at least one of:

one or more call characteristics of the receiving device;

one or more network conditions of the phone network and of the data network;

or

a cost to the sending device to establish the voice call between the sending device and the receiving device.

16. The system of claim 12 wherein the operation of choosing one of the phone network or the data network is further based on obtained user preference data that indicates one or more user preferences with respect to at least one of the one or more second characteristics, the obtained user preference data being associated with a receiving user of the receiving device, and a sending user of the sending device.

17. The system of claim 12 wherein the at least one processor is further configured to perform an operation comprising requesting the communication identity of the receiving device from the sending device, wherein the intermediate phone number is associated with the communication identity.

18. A non-transitory computer readable medium having stored thereon software instructions that, when executed by a processor, cause the processor to perform operations including:
