Thanks David for the help..

Here is my results:

dahdi_test -c 100
Opened pseudo dahdi interface, measuring accuracy...
99.998% 99.998% 99.604% 99.606% 100.000% 99.997% 99.608% 99.999%

99.999% 99.999%
--- Results after 98 passes ---
Best: 100.000% -- Worst: 99.604% -- Average: 99.965916%

we can see a few low drop to 99.6%

is there a way to fix this for a better result?

Will search a bit after this post, but if anyone had some experience with
this type of situation a little help will be welcome ;-)
