I was wondering why i hear from time to time conventional government frequencies, a "ringing" like you would hear if you placed a call. then some one would answer and the person would say reporting for duty etc blah blah. or other time it seemed like the person is checking their voicemail... what is that? and what are they using to activate the frequency? (a phone, radio??) why can't they just call in via a regular phone? and can anyone elaborate on this type of communication
