Notification of devices present in a communication session

1. A method comprising:

establishing, in response to a first communication request from a first caller device to a second caller device and a second communication request from the second caller device to the first caller device, an active session between the first caller device and the second caller device;

adding a third caller device to the active session in response to an additional communication request from the third caller device to the first caller device, the additional communication request occurring within a threshold time period of the first communication request or the second communication request; and

transmitting, to the second caller device, a notification indicating the presence of the third caller device in response to adding the third caller device.

2. The method of claim 1 , wherein the third caller device is added to the active session without additional input from the first caller device or the second caller device.

3. The method of claim 1 , wherein the third caller device is added to the active session based on stored indicia that a user of the third caller device is to communicate with a user of the first caller device and a user of the second caller device, wherein the stored indicia comprise at least one of a text message, an email message, or a calendar invite.

4. The method of claim 1 , wherein the third caller device is added to the active session based on a communication request from the first caller device to the second caller device, a communication request from the second caller device to the third caller device, and a communication request from the third caller device to the first caller device all occurring within a threshold time period of one another.

5. The method of claim 1 , wherein the first communication request and the second communication request are detected at a communication server comprising one or more proxy servers.

6. The method of claim 1 , wherein the active session is configured according to a configuration setting associated with the first caller device, and wherein the configuration setting comprises recording settings or time-limit settings.

7. A system comprising:

memory hardware; and

one or more processors configured to execute instructions stored in the memory hardware to:

establish, in response to a first communication request from a first caller device to a second caller device and a second communication request from the second caller device to the first caller device, an active session between the first caller device and the second caller device;

add a third caller device to the active session in response to an additional communication request from the third caller device to the first caller device, the additional communication request occurring within a threshold time period of the first communication request or the second communication request; and

transmit, to the second caller device, a notification indicating the presence of the third caller device in response to adding the third caller device.

8. The system of claim 7 , wherein the third caller device is added to the active session without additional input from the first caller device or the second caller device.

9. The system of claim 7 , wherein the third caller device is added to the active session based on stored indicia that a user of the third caller device is to communicate with a user of the first caller device and a user of the second caller device, wherein the stored indicia comprise at least one of a text message, an email message, or a calendar invite.

10. The system of claim 7 , wherein the third caller device is added to the active session based on a communication request from the first caller device to the second caller device, a communication request from the second caller device to the third caller device, and a communication request from the third caller device to the first caller device all occurring within a threshold time period of one another.

11. The system of claim 7 , wherein the active session is configured according to a configuration setting associated with the first caller device, and wherein the configuration setting comprises recording settings or time-limit settings.

12. At least one non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations comprising:

establishing, in response to a first communication request from a first caller device to a second caller device and a second communication request from the second caller device to the first caller device, an active session between the first caller device and the second caller device;

adding a third caller device to the active session in response to an additional communication request from the third caller device to the first caller device, the additional communication request occurring within a threshold time period of the first communication request or the second communication request; and

transmitting, to the second caller device, a notification indicating the presence of the third caller device in response to adding the third caller device.

13. The at least one computer readable medium of claim 12 , wherein the third caller device is added to the active session without additional input from the first caller device or the second caller device.

14. The at least one computer readable medium of claim 12 , wherein the third caller device is added to the active session based on stored indicia that a user of the third caller device is to communicate with a user of the first caller device and a user of the second caller device, wherein the stored indicia comprise at least one of a text message, an email message, or a calendar invite.

15. The at least one computer readable medium of claim 12 , wherein the third caller device is added to the active session based on a communication request from the first caller device to the second caller device, a communication request from the second caller device to the third caller device, and a communication request from the third caller device to the first caller device all occurring within a threshold time period of one another.

16. The at least one computer readable medium of claim 12 , wherein the first communication request and the second communication request are detected at a communication server comprising one or more proxy servers.

17. The at least one computer readable medium of claim 12 , wherein the active session is configured according to a configuration setting associated with the first caller device, and wherein the configuration setting comprises recording settings or time-limit settings.
