Free voicemail greetings
59 seconds of 17.1 kHz tone [mosquito]
17.1 kHz is above the 4 kHz upper frequency limit supported by the telephone network.
hurts my dam ear
Sampling rate of the phone network is 8khz. Any sounds above 4khz won't get through.
dont hear anything!!!
either this will be silent or annoying
if silent it will waste the callers time and minutes
if annoying it will STILL waste the callers time and minutes
entertaining either way
this is an awesome way to discourage a caller heard or otherwise. spooky would stand outside the FBI building citing other schizophrenic factoids or talk back to the moon
