I have only ever found the information in the driver source of on the 
CVS list as they have been added.

There is a list of them at the end of wctdm.c.

The non obvious ones I know about:

opermode=COUNTRY

Where COUNTRY is one from the list near the top of wctdm.c This will set 
the A.C. and D.C. line impedance on the FXO modules to suit the telecom 
standard used in that country. Default if not set, is FCC (US/Canada).

fxshonormode=1

If used, it must be in conjuction with the above. This will set the A.C. 
and D.C. line impedance on the FXS modules to match COUNTRY. Default if 
not set, is FCC (US/Canada).

lowpower=1

Reduces ringing volts on FXS to 50V peak.

boostringer=1

Boosts ringing volts on FXS to 89V peak.
