Filtering certain types of messages is quite easy:

if (is_method("INFO")) {
  # note: adjust to the proper content type used by AES/OCS
  if ($cT == "application/csta+xml") {
    sl_send_reply("415","Unsupported Media Type");
    exit;
  }
}


But there is no functionality to process csta content in Kamailio. If
there are other tools/libraries to process csta it should be quite easy
to process it using perl/lua/exec/python interface.
