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>

<div>Specifically, do you have ASA's doing site to site VPN's? By
default they do INSPECTION, which can drop SCCP packets they
don't recoginize.</div>

<p>This may have already been mentioned but building on
what Ryan said... probably between 6.1(2) and 8.6.x
you had a firmware change, probably from around 8.4ish
to 9.x. The sccp version changes, and it sounds like
you might have some firewall/security device in the
way that is not opening the ports because it is used
to the older version of skinny.</p>

<div>If the phone don't show a codec when the call
is set up then this isn't a typical routing
issue. The most obvious reason for the phone
not sending audio is it isn't getting the skinny
StartMediaTransmission message from CUCM.
<div>Have you looked at ccm traces for one of
these calls? When you do look at the
messages going to and from the phones in the
call. Compare/contrast what you see there to a
working call and call out what's different.</div>
<div><br>
</div>
<div>You can get a packet capture at the phone
as well to see what it is being told to send
to from CUCM. I'd also double check there's
nothing in the network doing sccp inspection.
You can get a simultaneous packet capture at
the phone and cucm to make sure every packet
leaving the server gets to the phone (intact).</div>

Everything seems to be as

One Phone got registered

Can't this ITL/CTL

[cisco-voip] After
upgrade to 8.6.2a
one way audio for
some calls-No codec
selected!</span></p>
</div>

<div><br>
</div>
<p class="MsoNormal">Hi 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 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>
In the remote site the
findings were inversed (no
receive codec and no
receive packets<br>
<br>
lease advise<br>
