Generating a tone w/ cadence is a piece of cake. *Detecting* a tone and cadence is a bit trickier. Nothing in FreeTDM (that I'm aware of) can detect both tone *and* cadence, which is why it works great in the US (which uses a combination of tones) as opposed to Mexico (which uses, I think 425Hz for everything). I'd ask Moises Silva if there's any plans to add the cadence detection. -MC On Mon, Apr 18, 2011 at 4:27 PM, Luis F Urrea <lfurrea@gmail.com> wrote:
Yes guru,
The point is that using tone_detect I am not able to specify cadence either.
I need to be able to detect a tone that plays 450Hz for 330ms and then silence for 330ms.
Strange thing is that on tones.conf generate tones do seem to specify cadence such as US busy
v=-7;(500,500,420,680)
I would interpret 420Hz for .5s and 680Hz for .5s
Is that how it is to be interpreted??
TIA

Hi Luis,
You could try the dialplan application tone_detect to detect the busy tone and hangup. http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_tone_detect

Hello, According to what I have found in regards the tones used for signaling on FreeTDM, it seems that anything set through DAHDI is ignored and specs from tones.conf are used instead. However I have not been able to properly detect a busy tone to be able to set an FXO back on hook once a busy tone is sniffed. tones.conf has the following references for busy tones [us]: generate-busy => v=-7;%(500,500,480,620) detect-busy=> 480,620 I would like to know if detect-busy takes into account the time frame that the frequencies are on (played) or off (not being played) and if there is somehow a way to specify this. Is there any default value for time on and time off? I appreciate your help!
