When I re-read my post, there is a danger that people thought that resetinterval fixes my problem. That's not what I meant.

What I meant to say was that, the resetinterval was all the time 
set as 'never' to begin with and the frequent channel reset problem 
was observed with 'resetinterval' set as 'never'. 

What I really need is someone who knows how to read the pri debug 
at http://www.geocities.com/mctiew/asterisk/bd2.txt, and perhaps 
can tell me what wrong with the said PRI line giving this problem 
***ONLY*** to asterisk but not giving any problem to other PBXes
while the same asterisk settings I have used was working perfectly 
on another PRI from the same network provider.

Perhaps someone could tell me how to increase the "tolerance" level
of asterisk towards PRI lines with lower quality.

Regards.
