I have not checked the source Iñaki, but I feal that it generates the the ACC 
records on reply or when the tm timer fires the sip-timeout, because there 
are no other way of getting the sip_code column filled if it is done JUST 
when the INVITE arrives.

If ...

UAC1      <->  P1                 <-> UAC2
INV          >  setflag(ACC)    >

And just when the INV arrives at P1 it generates the ACC record, that leave 
you on a situation that you will need 2 ACC ops to get the correct ACC 
record, one for writting down the INV ACC record, and other one when the 
reply (or the timeout) comes back, so you could update the INV ACC record for 
filling the sip_reason field.

I repeat .. I have not checked the source code, but for me the ACC record is 
better generated when you have the reply or timeout for the INV request, this 
is why the original poster does not get any ACC record on his DB, because it 
only t_replicate the INVITE and the BYE, so it will never get the replies, 
because he is not getting into the SIP-Path.
