I'm not sure if this is relevant, but in asterisk 1.4.22 (and many 1.4 
versions before it), if the other party has silence suppression turned 
on the two parties talking will get increasingly out of alignment with 
each other and the end of the file will be truncated.

Basically it would seem that asterisk takes one frame from each side of 
the conversation and writes it to the file. If one side stops sending 
frames the other side will queue up until more frames come.

Again, not sure if it's relevant but that's what keeps happening to my 
recordings.

I wonder if in your case perhaps the ringing time is causing your 
recordings to get out of whack and chopping the end off?
