just a guess here...

The simple answer is have you verified that loop timing is set up in 
zaptel.conf. If not in loop timing a slip could cause the drop.

Loop timing on span 2 as primary timing would be:
span=2,1,0,esf,b8zs

Does this happen at the same time every day? If so it does not sound 
like a timing issue. If at random times, it could be.
