<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>There was a tread that I googled for and could not find
about Asterisk being open to SIP DOS Attacks. I have a customer whose machine
was hammered last light by traffic on its SIP port causing the OS to use up its
resources. Namely number of open files. The discussion was around the fact
that the Sip protocol answers requests without regard to authentication. Can
anyone comment on this????</span></font></p>
