[Freeswitch-users] Tone detection How To

[Naveen Tamanam]

Hi nandy,

can we get  tone detection done, with out defining frequencies in
conf/autoload_configs/spandsp.
conf.xml. In my case I used event socket command(from external script),

tone_detect  8582g3b8-f7db-10e4-2ac4-c01885c1ffd3  tone_name
437,478,679,918,1357,1399,1593,1838

above frequencies are the peak frequencies that I took from logarithmic
spectrum(in audacity).
