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>
<br>
