hello everyone,
Last week I installed asterisk 1.2.24 with digium TE220B card. I have a problem with our PRI and Asterisk: the call be interrupted.It happens either PSTN-to-SIP or SIP-to-SIP,almost every call.
After spending several days searching on internet, I found a lot of
discussion about this issue and I have tried many,
but it still.I am totally new to Asterisk environment and suspect I am missing something somewhere

I would welcome any suggestions you may have.
Thank you in advance!

here is the log & .conf :

#####I get the log even no one use the asterisk. some one saied this because the network card and harddisk taking an interrupt for too long.This will cause the calls to be drop. But how can I stop it? I have disabled the inbound/outbound recordings,disabled some modules not used, but the issue still..
