Re: [Freeswitch-users] Skypiax: not able to detect Inband dtmf tones from pstn call?
Hi Anthony, Yes, The start_dtmf application is in the dialplan. One question I still have is will the Goertzel algorithm in libteletone_detect.c be able to detect and decode the DTMF tones once they have past through the PSTN and Skype network traversing various codecs? 1) They sound audible and clear. 2) A spectrum graph clearly shows the two frequencies. How bad does the signal need to degrade before the DTMF tones cannot be detected? Can you suggest a way to play recordings through the start_dtmf application. This way I can test various wave forms. ** BUG ** Why does samples=0? One thing I have noted is that when start_ivr_async.c calls: teletone_dtmf_detect(pvt-dtmf_detect, frame-data, frame-samples); for a skypiax call the samples=0 for a SIP call the samples=160 I hope this may help track down the problem. Perhaps in time with better understanding of the internal workings of fs and may be able to post solutions rather than problems? regards, Scott Torr On Tue, 22 Dec 2009 09:21 -0600, Anthony Minessale anthony.miness...@gmail.com wrote: add start_dtmf app to your dialplan before bridge to start the inband dtmf detector.

Re: [Freeswitch-users] Skypiax: not able to detect Inband dtmf tones from pstn call?
Yes, I noticed the Jira for the situation where the where the fs controlled skype client generates both an In Band audible DTMF tone and an API signal causing potential confusion for devices down the line. If only the skype client had an option not the generate the tone in the first place that would be good, but then I guess they (skype) think the client would only be an end device ;-) However that is not where I'm having a problem, as I'm purely dealing with 'In band' DTMF tones. The question I had on my mind was did the Skype codec faithfully transport the DTMF tones across the network? http://fs.torr.letterboxes.org/dtmf_compare.html From these comparisons I would have to say that there in no major filtering or distortion of the DTMF tones when transmitted across the Skype network. So I would have to say that you can receive calls from skypeIN with inband dtmfs.

Re: [Freeswitch-users] Skypiax: not able to detect Inband dtmf tones from pstn call?
Ooops, Had not seen you got it in the dialplan... try to move it after the answer and test again. Other than this, only thing that comes in my mind is that the conversion from the pstn to sip (skype partner that gives pstn access) to skype is ruining the dtmfs beyond recognition... but you said that at spectral analisys they're fine...

Re: [Freeswitch-users] Skypiax: not able to detect Inband dtmf tones from pstn call?
It is probably because mod_skypiax does not analize incoming audio looking for dtmf, because the normal call from a Skype client peer sends *both* inband and out of band (signaling) dtmf. So, I choose to only detect out of band (signaling) dtmfs, and ignore possible inband dtmfs (in the audio flow), so to have the most reliable source (signaling) and spare cpu (not analizing the incoming audio).
