Relayed Communication Channel Establishment

A recipient communication device comprising:

• at least one processor;
• and
• a memory storing software instructions executable by the at least one processor, the software instructions, when executed, causing the recipient communication device to:
• receive, from a relay allocation server, information identifying a first relay server allocated for use by both the recipient communication device and an initiating communication device for a communication session initiated by the initiating communication device;
• join the communication session using the first relay server;
• receive, from the first relay server, after joining the communication session, an instruction to request a different relay server;
• transmit, to the relay allocation server, a request for allocation of a second relay server for use by the recipient communication device for the communication session;
• receive, from the allocation server, information identifying the second relay server allocated for use by the recipient communication device for the communication session;
• and
• join the communication session using the second relay server.

A method for establishing a communication session, using a relay server, between a plurality of communication devices, the method comprising:

• by the relay server:
• receiving, from each communication device of the plurality of communication devices, a respective bind request;
• binding the communication session to each communication device of the plurality of communication devices, in response to the respective bind request;
• transmitting, to each communication device of the plurality of communication devices, an acknowledgment that all of the communication devices of the plurality of communication devices are bound to the communication session;
• and
• receiving communication data from a first communication device of the plurality of communication devices, wherein the receiving the communication data begins prior to the transmitting the acknowledgment.
