we support two types of DTMFs, sending by SIP INFO (this corresponds
to dtmfmode=info in asterisk) and sending DTMFs using RFC4733
(dtmfmode=rfc2833 in *). By default RFC4733 is enabled, to disable you
must uncheck it in Audio configuration its named telephone-event and
then SIP INFO is active.
Make sure you have the proper settings in asterisk for your account.
Hum, I've just discovered that when switching off telephony-event we
still use it and SIP INFO is never used. So for now you can test by
configuring your asterisk account with dtmfmode=rfc2833. I will check
these days whats the problem with configuring telephony event.

I tried to use SC with a conference bridge on my Asterisk (app_konference). The app has a feature to select the video using DTMF dialtones.
This works with Linphone - but unfortunately with SC it doesn't react. I can't tell if Asterisk can deal with inband DTMF, especially on the Speex codec.
How does SC send DTMF? Inband - as tones or with the signalling?
Thanks for help
