As one of those who raised this issue earlier (irc logs), I will write 
here my opinion on the possible implementation (suggested):
The channel hangup_handler that is called before closing the CDR session.

After trying different ways of catching the moments of completion of a 
Dial (with two channels) I found the use of hangup_handler the most 
Another problem is that in the time of the call CDR session has ALREADY 
been closed, but NO records in the CDR table YET.

I will be extremely glad if such an opportunity and don't need to write 
it in a separate table with the following pending merge.
