Steve,

After being delayed in the airport again on my way home I had some time to
think about this issue that we talked about.  Using the ZT_GET_PARAMS
ioctl you can retrieve the sigcap of each channel which will be:

for FXO:
wc->chans[x].sigcap = ZT_SIG_FXSKS | ZT_SIG_FXSLS | ZT_SIG_SF;

for FXS:
wc->chans[x].sigcap = ZT_SIG_FXOKS | ZT_SIG_FXOLS | ZT_SIG_FXOGS | \
ZT_SIG_SF | ZT_SIG_EM
