In the Line 1 tab, field "DTMF tx method", I had "auto"; after
searching the this in the manual, I changed it to "InBand+Info" (which
sends both audio info, and SIP info). Now it's working!

The "auto " setting for this parameter, "uses InBand or AVT based on
the outcome of codec negotiation", as per the SPA manual.

I would never imagined someone might want to change something like
this...

Thanks a lot!

PS - I still don't know what's the SIP info the DTMF tx method is
suppose to send out, but since it's doing what I want, and I haven't
noticed any other problem, I'm leaving that way.
