Thank you very much.
I tried sjphone setting clinet and asterisk as above and it seems to 
work. I will test it better in the next hours.

I had a look at meetme.c and i found a portion of code that manage dtmf

                if ((f->frametype == AST_FRAME_DTMF) && (confflags & 
CONFFLAG_EXIT_CONTEXT)) {
......
......

I think this part manage the case of meetme application is called with 
p, X or s option,
but maybe also (i'm not sure, i had not the time to study well enough 
the source, and over all i'm not a so good c programmer)
that this part of code prevents asterisk to broadcast the sound to other 
channels when it is not inband.

Sorry if my bad english make me not very clear.
Anyway, thank you very much to all for  your help.
