title: Asterisk CDR Report shows "s" in the destination field
body: <p>I have had issue on an platform for quite sometime now, when somebody calls in to ivr system, the cdr report destination field shows an 's' in place of the called number.
  The inbound route for the DID is set to the ivr menu.
  Here is my dial plan:
  "</p>
  
  <pre><code>exten =&gt; 800000031,1,Set(__FROM_DID=${EXTEN})
  exten =&gt; 800000031,n,Gosub(app-blacklist-check,s,1)
  exten =&gt; 800000031,n,ExecIf($[ "${CALLERID(name)}" = "" ] ?Set(CALLERID(name)=${CALLERID(num)}))
  exten =&gt; 800000031,n,Set(__CALLINGPRES_SV=${CALLERPRES()})
  exten =&gt; 800000031,n,Set(CALLERPRES()=allowed_not_screened)
  exten =&gt; 800000031,n(dest-ext),Goto(ivr-3,s,1)*
  </code></pre>
  
  <p>"</p>
  
  <p>I suspect the issue is on the last line but the file is not allowed to be edited directly.</p>
  
  <p>Will appreciate any help.</p>
