You need to add opermode=FRANCE

If you are using Didium FXS modules as well, with non 600 ohm phones, 
i.e. European TBR21 standard, you should add fxshonormode=1 as well. 
This will set the FXS impedance to whatever is specified in the opermode 
= parameter.

You can confirm this afterwards by checking dmesg for an entry showing:

Module 0: Installed -- AUTO FXO (FRANCE mode)
