        Thank you for the reply but the ieee paper we referred to used
        opensips and what i understood is that they implented the

              With OpenSIPS you can do only SIP related things, so usual
              security checks based on signaling. Like authentication,
              if certain external SIP domains are trustable, flood
              checks, pattern based detection, etc<br>
              <br>
              At SIP level you do not have access at the actual content
              (media) to see what about.<br>
              <br>
              Regards,<br>
