Summary:                    call disconnect due to power denial on startup
Description: 
I have not personally encounetered this with an X100P card, but helped
someone lately. As he has not filed a bug yet, I figure I will.

There are some PSTN providers who will indicate the begining of a call
with a short power denial. This is ignored by other FXO devices, but it
seems wcfxo detects it as a hangup signal if configured as 'fxsks'.

Workaround is to use LS signalling instead. However this means the end of
the call won't be properly detected, and thus it is sub-optimal.
