title: php-sip library - how to get the body of the SIP response
body: <p>I've just recently discovered the following lib: 
  <a href="https://code.google.com/p/php-sip/" rel="nofollow">https://code.google.com/p/php-sip/</a></p>
  
  <p>And I'm using it to send and rcv SIP messages.  So far so good. But in addition to just checking the value of the sip response, eg) 200 OK.  I need to get to the body of the response.  </p>
  
  <p>Has anyone found a way to do this? I'm currently reviewing the source code in PhpSIP.class.php but I don't see any public methods to getBody() or getResponse() etc. </p>
  
  <p>Maybe I'll have to write one?  I'm not sure.  but i thought I'd check in case someone else knows how to do this. 
  Thanks. </p>
