<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Many thanks for your fast response. I understand what you are saying, however even when I add “session:hangup()” as the first line
inside my hangup handler (function myHangupHook(s, status, arg)), that is prior to the pause of 5 seconds waiting for an event that never comes (at the moment) the resulting CDRs are based on when the Lua script completes (it seems) and not when the call disconnects.
I fully understand that this is a two way conversation (ie. Remote Disconnect received then Release sent and Release Complete received).

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Does this mean there is no way (within Lua under FreeSWITCH) to clear up a call correctly, then complete some extra code within the
Lua script, then end the Lua script and generate correct CDRs from within FreeSWITCH?<o:p></o:p></span></p>

this, however I thought I would first ask if I was missing something within FreeSWITCH.<o:p></o:p></span></p>

work when the remote end disconnects first}?<o:p></o:p></span></p>

<p class="MsoNormal">A more relevant answer is that during the hangup state the call is still in the process of hanging up, it isn't hung up and ended until the hangup_complete event. So your 5s sleep is extending the life of the call.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">What I noticed is that placing a call into FreeSWITCH via a SIP phone (calling 9101) and landing on myservice.lua everything processes as expected. If I hangup after 3 seconds
then I should expect the CDR to show ${billsec} = 3. However this is not the case since both ${duration} and ${billsec} are actually set once the Lua script completes (not based on HANGUP). So inside 1000.csv I see duration and billsec both having 8 seconds.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">You will see below that inside my hangup handler (function myHangupHook(s, status, arg)) I fire an event and wait up to 5000ms for an event to be returned (currently I am not returning
an event so the 5000ms will take place). This explains the extra 5 seconds after the 3 seconds of the call.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">My question is since FreeSWITCH knows that the HANGUP has taken place why is the ${billsec} not correct (ie. should be 3 seconds)?<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Is there a solution to this issue? Perhaps there is a different CDR variable that will contain the correct duration based on when HANGUP was actually received.<o:p></o:p></p>
