It should work fine just by swapping cards if your Sangoma driver 
install compiled with Hardware Echo Cancel support.  All you need to do 
now is edit the wanpipe conf file to include:
TDMV_HWEC       = YES

If it is a 2.4 Kernel then I would have my doubts about HWEC working out 
of the box since it requires DEVFS and some distros like RedHat don't 
have support for it by default.
