Lonnie,
I modified extensions.conf as suggested, but am still seeing the
segfault error. Below are snippets from /var/log/messages,
/var/log/asterisk/messages and the asterisk CLI. To test this, I used
my own fax machine connected to my WCTDM card and dialed my own
number.
This leads me to suspect NVFaxDetect again... can you suggest any
further troubleshooting?
