Before building Zaptel, you are grabbing the correct version of 
hpec_x86_32.o_shipped for your CPU and putting it in zaptel-1.2.13/hpec/ 
right?

It sounds to me like you've either not done that correctly, or something 
with the Sangoma build process is stopping the HPEC build working.

After building zaptel, run "strings zaptel.ko | grep  'High-Performance 
Echo Canceller'" and see if you get a line like:

"Digium High-Performance Echo Canceller, version %s"

If not, you're going to need to dig into the way your Zaptel is being 
built to see why the HPEC module is not being included.

Cheers,
    Nic.
