    Hi Ronald,<br>
    <br>
    Thanks for the useful information - find attached a patch that
    should fix the problem - please apply it, recompile and let me know
    if works ok - if yes, I will update on SVN.<br>
    <br>
    The crash seams to be triggered by a bogus SIP message where the
    parsing of the first line fails - and this message hits the pike
    route crashing in some parsing functions.<br>
    <br>
    Regards,<br>

              The crash happens on a reply and not a request - see the
              frame 14, where &quot;buf&quot; (the buffer containing the <br>
              sip message) shows a reply like text.<br>
              <br>
              But the is_method() should not crash at all....before
              diving into debugging:<br>
                  1) can you reproduce this crash ?<br>
                  2) before the crash, do you see any errors in the logs<br>
              <br>

                    <div> <br>

                    <div>Basically, I just want to check REGISTER
