title: Asterisk and Sipp UAS
body: <p>I'm trying to get sipp communicate with Asterisk in order to perform
  performance tests:</p>
  
  <p>I've been through these steps:</p>
  
  <p>1) In sip.conf</p>
  
  <pre><code>[sippuac]
  type=friend
  username=sippuac
  host=127.0.0.1
  port=5061
  context=test
  dtmfmode=rfc2833
  insecure=very
  canreinvite=no
  nat=yes
  
  [sippuas]
  type=friend
  username=sippuas
  host=127.0.0.1
  port=5062
  context=test
  dtmfmode=rfc2833
  insecure=very
  canreinvite=no
  nat=yes
  </code></pre>
  
  <p>2) In extensions.conf</p>
  
  <pre><code>[test]
  exten=&gt;s,1,Dial(SIP/sippuas,20)
  </code></pre>
  
  <p>3) Running SIPp</p>
  
  <pre><code>sipp -sn uas -rsa 127.0.0.1:5060 -p 5062 -i 127.0.0.1 -mp 6001
  
  sipp -sn uac 127.0.0.1:5060 -s s -p 5061 -i 127.0.0.1
  </code></pre>
  
  <p>Finally I get on Asterisk :</p>

  <p>How can I solve this and make the UAS receive the calls ?</p>
  
  <p>Thanks for your help !</p>
