Seems fairly easy to recreate then; can you get q.931 logs from Asterisk to 
try and help us out?  That'll let us know if one side or the other is 
dropping them on purpose, and if you can so easily recreate the problem it 
might be possible to beg/borrow/steal a proper T1 test set (your telco should 
offer this in the first place) to make sure you're not experiencing anything 
unusual on the physical link.
