A summary of some of the mistakes in this thread, as it was full of
them.

An FXO module needs FXS signalling:

 fxsls=3

And probably fxsks=3: I'm not sure whether or not KS is used in the
French telco .

Didn't you know this obvious fact?

And what is the channel number of this module?

The card reports that first three slots are unused, and only slot 4 is
used. You should have known that this is a zero-based counting, whereas
the counting of Zaptel channels is 1-based.

Luckily for you you have just one card, and didn't need any further
offsets calculations.

Those two tiny this are obvious to us who havve been messing long enough
with Zaptel. However they are far from being intuitive.

My suggestions: either:

* Use genzaptelconf from xpp/utils/genzaptelconf to save you from this
  guesswork.

Or:

* Apply http://bugs.digium.com/view.php?id=7613

(preferably with some optimizations from the wctdm driver itself, but
the latter is clearly not my department).
