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?
They aren't really sending 2833.
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?
I bet they don't know how to config their switch to do 2833. /b
