There isn't much to the step-by-step -- in the ztconfig.h file you will see the various echo cancellation algorithm defines: /* * Pick your echo canceller: MARK2, MARK3, STEVE, or STEVE2 :) */ /* #define ECHO_CAN_STEVE */ /* #define ECHO_CAN_STEVE2 */ /* #define ECHO_CAN_MARK */ #define ECHO_CAN_MARK2 /* #define ECHO_CAN_MARK3 */ In the example MARK2's defined. The general consensus is that MARK2's the best, IIRC. There is also the agressive cancellation code, which I think practically everyone wants but it breaks things like POS machines and faxes, although I think now if the driver hears a fax tone it will disable the aggressive code: /* * Uncomment for aggressive residual echo supression under * MARK2 echo canceller */ /* #define AGGRESSIVE_SUPPRESSOR */ Once you've made the changes, save 'em and make clean && make && make install.
