[Freeswitch-users] DTMF: Mute sound for the other side?

[Dennis]

ok, i will try this, but how can it be possible, that inband tones are
audible in conference, when we do not even have start_dtmf activated?

i just don't understand, why it must be dtmf inband, if the tones are
audible and how they can be audible, if start_dtmf is not set.
is it, because the carrier just sends them as normal sound, which is
played as a tone, without beeing used for dtmf?
