    Hi all,<br>
    well, i have disabled any kind inspection on the ASA.Isn't that
    enough?<br>
    ASA does NOT NAT. Isn't that enough?<br>
    However, i have to check some corporate linux based vpn endpoints.<br>

                                                          all,<br>
                                                          here is a
                                                          tough one! <br>
                                                          I recently
                                                          upgraded my
                                                          6.1 cluster to
                                                          8.6.2a.<br>
                                                          Since my
                                                          Hardware was
                                                          7825H3
                                                          typically it
                                                          was not an
                                                          upgrade rather
                                                          than a fresh
                                                          install using
                                                          a usb drive
                                                          (cisco has
                                                          this procedure
                                                          for these type
                                                          of servers)<br>
                                                          The upgrade
                                                          was smooth for
                                                          pub and one
                                                          sub.<br>
                                                          All phones
                                                          reregistered
                                                          and upgraded.<br>
                                                          In the main
                                                          site there are
                                                          20 devices
                                                          (7975, 7961,
                                                          7911) and at 2
                                                          remote sites 2
                                                          devices (one
                                                          at each site).<br>
                                                          After the
                                                          upgrade:<br>
                                                          all phones in
                                                          the main site
                                                          can talk to
                                                          each other.<br>
                                                          The two remote
                                                          phones can
                                                          talk to each
                                                          other.<br>
                                                          Each of the

                                                          when talking
                                                          to main site
                                                          have one way
                                                          audio!<br>
                                                          The remote
                                                          site does not
                                                          hear the main
                                                          site always.<br>
                                                          There is no
                                                          firewall/NAT 
                                                          between the
                                                          sites.<br>
                                                          I noticed that
                                                          there is no
                                                          codec selected
                                                          for the audio
                                                          stream that
                                                          has the
                                                          problems and
                                                          so no transmit
                                                          (or received
                                                          packets for
                                                          the other).<br>
                                                          And i explain:
