Run zttool and see if you the T1 card is missing interrupts. If so, put
the following statement in your rc.local :
# unmask interrupts
/sbin/hdparm -u1 /dev/hda
This will tell the ide driver not to mask interrupts while servicing disk
i/o and the missing interrupts on your T1 card will likely go away.
If this isn't the problem, zttool might still give you a hint if there are
problems on the PRI itself.

I've got a 4 port T1 card in my Asterisk box with a PRI from Qwest as
my PSTN interface. I'm experiencing random dropped calls on the
various SIP devices I have tested. Network connectivity to the SIP
devices looks ok, and I have tried a variety of the devices including
all of the following.
Grandstream 286
Grandstresm 486
Sipura SPA 1000
Mediatrix 2102
Some example lines from my logs which may indicate a problem
