Thanks for replying, hope you don't mind I'm sending this to the list.

The driver has international support already, it seems it was added in what
has become SVN revision 197 from almost three years ago
("Internationalize FXO"):

http://svn.digium.com/view/zaptel/trunk/wcfxo.c?r1=190&r2=197

is in that code that I see the bug (erroneously specifying registers
offset in hexadecimal),
maybe I'm wrong and the code targets a different DAA (I'm using Si3014
which is intl.) but
it's strange the other acceses to the chip the driver performs respect
the datasheet.

If I'm right it seems no correct initialization of these registers has
been done since then (I
don't know how bad can it be. perhaps it doesn't affect FCC-compliant setups).
