<p class="MsoNormal"><span lang="EN-US">We are using FreeSWITCH as a third-party recording application, i.e. we are receiving SIP calls with the complete audio of conversations taking place on another switch and we are saving this audio to a file. To achieve
this we are using a simple script similar to this:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New"">session:answer()<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New"">while(session:ready() == true) do<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""> test = session:recordFile("/usr/local/freeswitch/recordings/test.wav", 18000, 0, 300)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""> session:setAutoHangup(false)<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""> session:hangup()<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New"">end<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">This script will be invoked by the following dialplan:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""><extension name="Recording"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""> <condition field="destination_number" expression=".*"><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Courier New""> <action application="lua" data="record.lua"/><o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Basically it seems to work quite well, but sometimes there are missing audio at the end of the recorded file. Usually it’s only a few seconds, but sometimes it seems to be more. (It’s like the recording sometimes goes
behind the real call and when the hangup event is received the remaining audio is discarded.)
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">What could be the reason for this behavior? Is there something wrong with the script or is there a better way to achieve our goal?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
