Claim:
1. A system, comprising: a processor; a microphone in communication with the processor; a speaker in communication with the processor; a data relay transceiver in communication with the processor; and a memory in communication with the processor and storing instructions that, when executed by the processor, cause the processor to: determine a threshold based on an average amplitude of a signal provided to the speaker by the data relay transceiver; sample the amplitude of the signal; and disable the microphone and enable the speaker if the sampled amplitude is greater than the threshold wherein the memory further stores instructions to cause the processor to sample a plurality of amplitudes of the signal, wherein each of the plurality of samplings is delayed by a predetermined period of time; wherein the memory further stores instructions to cause the processor to disable the microphone and enable the speaker only when the amplitude of at least two of the plurality of samplings are greater than the threshold.
