Thank you again Brian. The reason why I want to test with inband dtmf is that
in the real environment FS will be behind a conventional ISDN PBX which will
work as a gateway to the ISDN Network. So I do not know if the PBX will do
something like a translation between DTMF Tones to rfc and backwars.
If you have experience with this any help will be very welcome....Guido

Well the best option is to NOT use inband at all if possible. And use RFC2833
which eyebeam/xlite support as do most providers out there... You do not HAVE
to start_dtmf on sip channels unless they only send the DTMF inband.
set the dtmf-type back to rfc2833 and restart FS.

First thanks for your reply.
I have subscribed to all Events, so this can't be the mistake. I sent start_
dtmf app to FreeSwitch in caller channel and the wiki says that you have to do
this on sip channels to enable inband dtmf. I checked sofia.conf and I have
found that param dtmf-type is commented out. Would it be helpful to set this to
"info"? I think setting it to "rfc2833" would not be very meanigfull.
I will try to update to svn trunk tomorrow.
Again thanks for first help...Guido
