Failover based on sending communications between different domains

A method comprising:

• a. detecting in a primary network domain controller a failure on a first communication channel of a primary network;
• b. sending from a first communication device, comprising a plurality of communication devices, a communication directed to a second communication device, wherein the communication is sent to the primary network on a second communication channel;
• c. sending in the primary network domain controller, the communication directed to the second communication device via a third communication channel, wherein the third communication channel is between the primary network and a secondary network;
• d. sending in a secondary domain controller the communication to the second communication device;
• e. arbitrating in the plurality of communication devices to determine a master node of the plurality of communication devices;
• and
• f. sending in the master node of the plurality of communication devices the communication directed to the second communication device.

A system comprising:

• a. a first communication device configured to detect a failure on a first communication channel of a primary network and send from a communication directed to a second communication device, wherein the communication is sent to a secondary network;
• b. a secondary domain controller configured to send the communication to the primary network via a second communication channel, wherein the second communication channel is between the primary network and the secondary network, and to send the communication to the primary network based on matching an identifier in the communication, wherein the identifier identifies at least one of the following:
• the first communication device, a master node, a user of the first communication device, or a user of the master node;
• and
• c. a primary network domain controller configured to send the communication to the second communication device.

A system comprising:

• a. a primary network domain controller configured to detect a failure on a first communication channel of a primary network and send a communication directed to a second communication device via a third communication channel, wherein the third communication channel is between the primary network and a secondary network;
• b. a first communication device, comprising a plurality of communication devices, configured to send the communication directed to the second communication device, wherein the communication is sent to the primary network on a second communication channel;
• c. a secondary domain controller configured to send the communication to the second communication device;
• d. arbitrating in the plurality of communication devices to determine a master node of the plurality of communication devices;
• and
• e. sending in the master node of the plurality of communication devices the communication directed to the second communication device.
