Since the last firmware update we are getting some issues on the switch policies. We have several cisco telephones in our worldwide company, and somehow the traffic is blocked on some phones so the do not register anymore to our call manager. We have set the parameter to bypass authentication but that does not seem to work anymore.
Any ideas where to look now... I can see traffic go with wireshark towards the switch/phone, but the device/phone responds with a TCP retransmission...
Just saw the update on the firmware
Waiting for this to be installed on our switches
