The original poster want to do accounting based only on SIP signaling, just 
doing some kind of t_replicate only of the INVITE and BYE request from the 
main proxy to an "external" one.
That's imposible to do, not only because it will be a very poorly accurate 
accounting but also because the ACC module does not "account" based on the 
initial INVITE message but on the reply (positive or negative) or on the 
timeout (so no reply).

I mean ...

UAC          <->         Proxy         <->     UAC2
INVITE         >
                        setflag(ACC)
                                                  <     200 OK
                        write(db,acc_record)
200 OK        <

Hope I have explained it ok.
