    Hi Mike,<br>
    i have completely disabled inspection on an ASA that i have that
    does only routing.<br>
    The question is: has something changed in SCCP negotiation in CUCM
    8.6?<br>
    The whole setup has been working for 3 years!!<br>

                                              here is a tough one! <br>
                                              I recently upgraded my 6.1

                                              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 remote phones
                                              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: in an
                                              active call between the
                                              main site and a remote i
                                              checked the send/received
                                              codecs and statistics.<br>
                                              the main site had g711 as
                                              received codec and of
                                              course the received
                                              packets augmented<br>
                                              but there was none as send
                                              codec and of course no
                                              packets transmited.<br>
