So what your are looking it's to do some kind of callthrought, but don't whant the caller to hear the DTMF
This is what I'm trying to achieve. And to be clear the call is initiated from an Android phone. The DTMF digits are part of the dial string of the form <phone-number>,<some-digits># I'm not disagreeing with your comment that DTMF tones are audible at the smartphone end. I may have been approaching this problem in the wrong way, but what I do know is that with the previous system - which wasn't using Freeswitch, but Twilio we could successfully make calls from an android device and the DTMF tones were not audible at the android end. So what is going on that makes that possible? On Fri, 7 Jul 2017 at 20:43 Raúl Alexis Betancor Santana < rbetancor@gmail.com> wrote:

Yes, I mean that the caller who is pressing the buttons (although in this case the button presses are automated as they are included at the end of the original dial string).
The reason why I believe this is possible is that in a different set-up, not using Freeswitch (rather using Twilio) we were successfully able to transmit DTMFs (as part of dial string) and they were not audible to the caller.
I'm just wondering as I type this, if the fact that they were part of the dial string is significant?

Do you mead that the user ON THE OTHER END doesn't hear anything? Because I believe most devices will generate their own audible tone on the generating end.

Thanks for that, that is useful info.
I posted a separate, but related question that you might have some suggestions about.
Namely I'm assuming that for RFC-2833 DTMFs Freeswitch is generating a corresponding tone for the received DTMF (I don't know if this is actually true or not). If this is the case whether it is possible to disable this tone so that basically a user pressing a key (that generates a DTMF) doesn't hear anything.
Thanks

RFC-2833 sends the DTMF as a special packet within the RTP stream. SIP-INFO sends it in the SIP dialog. INBAND DTMF come as a series of packets within the RTP stream that must be analyzed to find the frequencies corresponding to the different DTMF. I believe spandsp takes cares of this.
