<p class="MsoNormal">I’ve noticed that accounting for missed calls is generated for the main branch (1<sup>st</sup> destination) only, whether this is a 486 response or a 408 on expiry of the ‘fr_inv_timer’. After a receiving a failure another destination
is created/tried by the script, we are allowing up to 4 serial forks. I do see the 183 message for each fork and if the call is answered then the acc table is updated correctly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">How can I log the missed call response for each fork, or only log the final failure message for the call? Logging failed transactions seems to put them into the main acc table and not the missed call table which I would have expected.

<p class="MsoNormal">Thanks,<o:p></o:p></p>
