Initiating a collaboration session between devices using an audible message

A method, comprising:

• broadcasting an audible message from a first computing device over a first channel, wherein the audible message comprises an audible noise broadcasted using a plurality of frequencies and the audible message comprises a first unique identifier indicative of the first computing device, wherein the audible message is received by a plurality of second computing devices that are within audible range from the first computing device, wherein the plurality of second computing devices extract the first unique identifier from the received audible message;
• receiving, at the first computing device, an electronic acknowledgment message from each of the plurality of second computing devices over a second channel, wherein each acknowledgment message comprises a second unique identifier indicative of one of the plurality of second computing devices and the second channel is distinct from the first channel, wherein the second channel comprises at least one frequency in a wireless network;
• identifying, by the first computing device, each of the plurality of second computing devices based on the second unique identifier in the respective acknowledgment messages;
• and
• initiating a collaboration session between the first computing device and the plurality of second computing devices by transmitting an electronic collaboration message from the first computing device to the plurality of second computing devices, wherein the collaboration message automatically causes the plurality of second computing devices to enter the collaboration session.

A non-transitory computer readable medium comprising logic, the logic, when executed by a processor, operable to:

• broadcast an audible message from a first computing device over a first channel, wherein the audible message comprises an audible noise broadcasted using a plurality of frequencies and the audible message comprises a first unique identifier indicative of the first computing device, wherein the audible message is received by a plurality of second computing devices that are within audible range from the first computing device, wherein the plurality of second computing devices extract the first unique identifier from the received audible message;
• receive, at the first computing device, an electronic acknowledgment message from each of the plurality of second computing devices over a second channel, wherein each acknowledgment message comprises a second unique identifier indicative of one of the plurality of second computing devices and the second channel is distinct from the first channel, wherein the second channel comprises at least one frequency in a wireless network;
• identify, by the first computing device, each of the plurality of second computing devices based on the second unique identifier in the respective acknowledgment messages;
• and
• initiate a collaboration session between the first computing device and the plurality of second computing devices by transmitting an electronic collaboration message from the first computing device to the plurality of second computing devices, wherein the collaboration message automatically causes the plurality of second computing devices to enter the collaboration session.
