[asterisk-users] PRI problem

Thanks for the tip, Harry. I will try that when I have exhausted all 
avenue. My problem is that if I upgrade to 1.4.24 and DAHDI, I'll break 
other stuffs.

In my current set up, the PRI did work for a long period of time (7 
hours) before going into this unreliable mode (up and down). I'm getting 
the telco technicians to check on this first because I believe the 
problem comes from their side. During the few hours when it is working, 
I am able to make and receive calls. So I don't think the issue lies 
with Asterisk.

Regards,
Steve
