<p class="MsoNormal">To FreeSWITCH users,<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I am currently experimenting with Lua scripts on FreeSWITCH (latest build) and found an interesting issue with FreeSWITCH default CDRs (inside log/cdr-csv/1000.csv).<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">See below for my simple Lua script called from a diaplan as follows:<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal"><include><u></u><u></u></p>
<p class="MsoNormal"> <!-- To test Lua script --><u></u><u></u></p>
<p class="MsoNormal"> <extension name="ivr_demo"><u></u><u></u></p>
<p class="MsoNormal"> <condition field="destination_number" expression="^(9101)$"><u></u><u></u></p>
<p class="MsoNormal"> <action application="lua" data="myservice.lua"/>
<u></u><u></u></p>
<p class="MsoNormal"> </condition><u></u><u></u></p>
<p class="MsoNormal"> </extension><u></u><u></u></p>
<p class="MsoNormal"></include><u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">My question is since FreeSWITCH knows that the HANGUP has taken place why is the ${billsec} not correct (ie. should be 3 seconds)?<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I tried adding “session:hangup()” as the first line inside my hangup handler (function myHangupHook(s, status, arg)) and this made no difference.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">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.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Thanks in advance for any assistance with this.<u></u><u></u></p>
