About the best thing that you can do to reduce Echo on the X101P and X100P 
cards is to;

1. Set the following in zapata.conf;

echocancel=128
echocancelwhenbridged=no
echotraining=800

2. Enable aggressive echo cancellation in zaptel's zconfig.h file;

/*
 * Uncomment for aggressive residual echo supression under 
 * MARK2 echo canceller
 */
#define AGGRESSIVE_SUPPRESSOR

I've had much better luck at killing Echo issues with the above 
suggestions, on both my P133 X101P box as well as my TE405P based PRI 
Gateways. It doesn't solve all the issues, but it does help quite 
noticeably.
