hi,

i am having a small problem with the dtmf-sounds...

if i press a dtmf digit while i am bridged with another leg, the other
side will hear the dtmf sound.
this is very annoying and even worse in a conference, when multiple
people can press dtmf digits (for (un-)muting themselves or using
other functions).

is there a way, to NOT let the other side hear the dtmf sound (but of
course still make fs listening to it)?


thanks for the help
dennis

1) don't use inband tones for dtmf.
2) post a bounty to have FS clip the audio for x milliseconds when a tone is detected. (you will still hear faint clicks between the start of the tone and when the clipping activates)

we are not using inband tones. we are using rfc2833.

is it still neccessary, to do some extra programming? if yes: isn't
there a way for fs to recognize, that there is a rfc2833 and simply
does not play it back for the others?

If your in a conference and your hearing other people hitting dtmf
digits that IS inband, it means that the place upstream that is doing
inband to 2833 conversion is not properly clipping the dtmf, this
probably needs to be fixed on that device.

that is interesting. we are receiving the dtmf digits over 2833. might
it be possible, that we receive 2833 AND inband (we asked our carrier
for 2833, because we had problems with inband and fs - and we got it)?

is there something we can setup in fs or is it a problem wich only our
carrier can solve?

Well if they are sending both they are broken. I would call and yell
at them and beat them with a cluebat.

i can't tell, if they are sending both, but it seems so. we get 2833
for sure. they were kind enough to give it to us, because inband seems
to be quite unreliable over sip.

how can in find out, if both are coming and is there a way to "block"
inband to test?

perhaps we need both: if we bridge an inbound with another ivr on the
outbound side, which is not sip and does not understand 2833, we need
to pass inband through or something like this. or am i wrong with
this?

turn on the start_dtmf app and dial digits from the outside.. if you
get duplicate digits then they are sending both.

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?
