Are your phones running firmware you expect them to be?

Hi all,
here is a tough one!
I recently upgraded my 6.1 cluster to 8.6.2a.
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)
The upgrade was smooth for pub and one sub.
All phones reregistered and upgraded.
In the main site there are 20 devices (7975, 7961, 7911) and at 2 remote sites 2 devices (one at each site).
After the upgrade:
all phones in the main site can talk to each other.
The two remote phones can talk to each other.
Each of the remote phones when talking to main site have one way audio!
The remote site does not hear the main site always.
There is no firewall/NAT  between the sites.
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).
And i explain: in an active call between the main site and a remote i checked the send/received codecs and statistics.
the main site had g711 as received codec and of course the received packets augmented
but there was none as send codec and of course no packets transmited.
In the remote site the findings were inversed (no receive codec and no receive packets

lease advise
