Hi Alex, Referring to this wiki: https://wiki.freeswitch.org/wiki/Mod_spandsp#Call_Progress You need to tune the detector (record the tone and make a freq analysis). Take note the series of <element /> in spandsp.conf. That's the sequence of tones to be detected. The min/max is the duration of every tone. In the dialplan app start_tone_detect, the data=1 refers to the <descriptor name="1">. You can create your own set of progress tones. Good luck. /Nandy On Mon, Jun 20, 2016 at 10:58 PM, Alexandru Covalschi <568691@gmail.com> wrote:
Thanks for your reply Christopher!
Can you please specify how should I edit spandsp.conf (tones section) to add my tone? I was trying for hours but didn't get any result, I just can't get the logic and I'm struggling.
Cheers, Alex

Hi list,
I have an issue using tone_detect. The thing is I must detect two very short tones - 1400 Hz and 2300 Hz 100ms coming one after another (with 100 ms pause I suppose) after ~2 seconds the call is answered. I have pretty accurate wav file, in audacity I see pikes are 1400 and 2296. I've seen that in spandsp sources it is said that accuracy is ~3% so that should be enough, However tones aren't detected even if I set:
<action application="tone_detect" data="tone_1_0 1395 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_0 2295 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_1 1396 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_1 2296 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_2 1397 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_2 2297 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_3 1398 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_3 2298 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_4 1399 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_4 2299 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_5 1400 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_5 2300 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_6 1401 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_6 2301 r 0 set tone_second=true 1"/> <action application="tone_detect" data="tone_1_7 1402 r 0 set tone_first=true 1"/> <action application="tone_detect" data="tone_2_7 2302 r 0 set tone_second=true 1"/>
Tried to do same using spandsp_start_tone_detect(), but I have no idea how to edit spandsp.conf to add a tone matching my needs.
Can someone give me any clue? Any parameter I need to change in sources to obtain what I need?
