Method and system for moving phone call participation between carrier and data networks

A method of providing a communication session and coordination of signaling for the communication session is performed by a server, the method comprising:

• running a central service on a media mixing module of the server that coordinates a signaling path between a first client device and a second client device;
• receiving a first data signal and a second data signal from the first client device at the media mixing module of the server, the first data signal and the second data signal including media data from the first client device and an identifier of the second client device, wherein the first data signal is received over either one of a carrier network or a data network, and the second data signal is received over the other of the carrier network or the data network;
• conducting a first phone call between the first client device and the media mixing module of the server based on the first data signal and the second data signal received from the first client device;
• initiating a second phone call from the media mixing module of the server to the second client device based on the identifier included in the first data signal and the second data signal from the first client device;
• connecting the second client device to the media mixing module of the server over the second phone call;
• receiving a third data signal from the second client device at the media mixing module of the server, the third data signal including media data from the second client device;
• joining each of the first data signal and the second data signal of the first client device with the third data signal of the second client device in a media mixing communication session;
• after joining each of the first data signal and the second data signal of the first client device with the third data signal of the second client device, monitoring whether each of the first data signal and the second data signal has an active connection, and monitoring whether the third data signal has an active connection;
• and
• maintaining the media mixing communication session between the first client device and the second client device based on the monitoring of the active connection of each of the first data signal and the second data signal, and based on the monitoring of the active connection of the third data signal.

A non-transitory computer readable storage device for providing a media mixing communication session between a plurality of client devices, the computer readable storage device having computer executable instructions for performing the steps of:

• running a central service on a media mixing module of a server that coordinates a signaling path between each of the plurality of client devices;
• receiving a first data signal and a second data signal from a first client device at the media mixing module of the server, the first data signal and the second data signal including media data from the first client device and an identifier of a second client device, wherein the first data signal is received over either one of a carrier network or a data network, and the second data signal is received over the other of the carrier network or the data network;
• conducting a first phone call between the first client device and the media mixing module of the server based on the first data signal and the second data signal received from the first client device;
• initiating a second phone call from the media mixing module of the server to the second client device based on the identifier included in the first data signal and the second data signal from the first client device;
• connecting the second client device to the media mixing module of the server over the second phone call;
• receiving a third data signal from the second client device at the media mixing module of the server, the third data signal including media data from the second client device;
• joining each of the first data signal and the second data signal of the first client device with the third data signal of the second client device in the media mixing communication session;
• after joining each of the first data signal and the second data signal of the first client device with the third data signal of the second client device, monitoring whether each of the first data signal and the second data signal has an active connection, and monitoring whether the third data signal has an active connection;
• and
• maintaining the media mixing communication session between the first client device and the second client device based on the monitoring of the active connection of each of the first data signal and the second data signal, and based on the monitoring of the active connection of the third data signal.
