Hi Paul,
Recent wanpipe drivers for a104d seems to be 
beta7-2.3.4(http://sangoma.editme.com/wanpipe-linux-drivers#beta). Only 
directory that contains oct6100_api.h is:
which is apparently diffrent from what is expected by configure script:
if [[ -f "$ac_cv_use_wphwec/wanec_iface.h" -a -f 
"$ac_cv_use_wphwec/oct6100_api/oct6100api/oct6100_api.h" ]]; then
     WANPIPE_HWEC_INC="-DHAVE_WANPIPE_HWEC -I$ac_cv_use_wphwec 

After changing that, yate compiles and starts without complaining that 
it can't enable hardware DTMF detection. Alas only random noise is heard 
on isdn channel.
