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? On Fri, 7 Jul 2017 at 20:05 Guillermo Ruiz Camauer <grcamauer@gmail.com> wrote:
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.

From the source:
switch(dtmf->source) {
case SWITCH_DTMF_INBAND_AUDIO: /* From audio */
dtmf_source_str = "INBAND_AUDIO";
break;
case SWITCH_DTMF_RTP: /* From RTP as a telephone event */
dtmf_source_str = "RTP";
break;
case SWITCH_DTMF_ENDPOINT: /* From endpoint signaling */
dtmf_source_str = "ENDPOINT";

case SWITCH_DTMF_APP: /* Injected by application */
dtmf_source_str = "APP";
break;
case SWITCH_DTMF_UNKNOWN: /* Unknown source */
default:
dtmf_source_str = "UNKNOWN";
break;

Thanks Brian,
Having done that it says
DTMF-Source: RTP
So I assume that means that the DTMF is in-band, is that right?
