          <br>
          Such compressing of the body is not standard (AFAIK, so please
          correct <br>
          me) - so something like this will work only between 2 OpenSIPS
          (one to <br>
          compress, the other to decompress) .....Which will
          tremendously limit <br>
          the usability of this feature. <br>
          <br>
          Is there something wrong in what I'm saying ? <br>
