Hi, I'm doing some tests between 2 FS to understand how the tone_detect application works. I'm trying to detect a SIT tone, but I can't seem to detect the 3 tones. I only get the first activated tone. If I have all tones activated - - - > I detect only the first tone of my wav file. If I have 2nd segment tones and up activated - - - > I detect only the second tone of my wav file. If I have the 3rd segment tones activated - - - > I detect only the third tone of my wav file. I see that tone_detect can detect all 3 tones, but never at the same time. Does anyone have an idea of what I could be doing wrong ? Thanks ! I'm using FreeSWITCH Version 1.0.trunk (14397).
