Hello,<div><br></div><div>   I have one LUA script that make calls to one custom FS app. That app sets up some session channel variables and makes an outgoing call:</div><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px">

<div><div>if(caller_channel = switch_core_session_get_channel(session)){</div></div><div><div>   switch_channel_set_variable(caller_channel, &quot;var&quot;, &quot;val&quot;)</div></div><div><div>}</div></div></blockquote>

<div><div><br></div><div>   If the caller hangs up the call, the app returns and I try to get the val of var as:</div></div><div><br></div><blockquote style="margin:0 0 0 40px;border:none;padding:0px"><div>session:getVariable(&quot;var&quot;)</div>

</blockquote><div><br></div><div>   but a nil value is returned. Do you know why?</div><div><br></div><div>Regards</div><div><br></div>
