<p class="MsoNormal"><span lang="NL">Hi Guys,</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="NL"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">I am in an urgent matter an need help with something, I am using an ESL inbound connection to setup a new call.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">It works fine on successful answered calls.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">I am using the uuid_getvar api function whilst dialing to get the endpoint_disposition of the dialing uuid to check when a call is answered.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">So when it’s answered it will return “ANSWER”.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">The problem with this is that if an attempt fails, the endpoint disposition cannot be read with the uuid_getvar function because the dialing session is already gone.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">What is the best way to get the result in realtime?, I really need to know the reason it failed.</span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US"> </span><o:p></o:p></p>
<p class="MsoNormal"><span lang="EN-US">Thanks for your help,</span><o:p></o:p></p>
