Hi Alex,
yes, locally generated BYEs I was trying to avoid the unique constraint approach as it is not very elegant. I tried, AVPs, they are not accessible on the event_route[tm:local-request]
however, your idea on $dlg_vars was spot on, why didn't i think of that. Thanks a bunch!

Oh, you were talking about the BYEs that are internally generated by 'dialog'. In that case, ignore my advice; it's not applicable, because locally generated BYEs will not have the RR header and this won't work.
In those situations, in my personal opinion, your best bet is to use a database-side UNIQUE constraint or trigger to ensure that only one BYE is logged for any given Call-ID. Otherwise, you're going to have to do some sort of internal statekeeping with 'htable' or what have you.
You might be able to set $dlg_vars[1] indicating who is the callee and who is the caller, as well. However, I am not sure if you will have access to them inside the local event_route. That's a good question.

I have a situation here,
when a dialog expires, it sends a BYE to both call legs and this does not generate an entry on acc table.
however, when i use acc_db_request() on event_route[tm:local-request], i get 2 entries on acc, 1 for the downstream, and 1 for the upstream.
is there a way of handling this so i can only get 1 BYE on acc?
You could take advantage of the rr module's is_direction() function:
