title: Get session variable using session uuid
body: <p>How am i able to get session variable using just session uuid (using lua).</p>
  
  <p>So for example, we have session of leg_a (when someone connect sip phone). When other side answers, we will be within other session (session of leg_b).</p>
  
  <p>Using just, </p>
  
  <pre><code>session:getVariable("variable_name") 
  </code></pre>
  
  <p>will not help in that case because session refers to the current session.</p>
  
  <p>How am i able to use lua to get variable name when i know session uuid. (so i can get other sessions variable, even we are within current session which is different)</p>
  
  <p>Is there some kind of function where I am able to provide two parameteres, variable name and session uuid?</p>
