On the customers site, we have a Cisco infrastructure using Cisco 3750 switches and Nortel VOIP phones. The strange thing is, every now and then, a phone will drop out and freeze for no reason, yet the data side of the network, which passes through the phone, still operates fine ?. On other cases, the interface will jsut say Line Protocol down ( not connected)
To get the voice side back working, and sometimes the data, it is a case of breaking the POE connection to reboot the phone ( Shut/No shut). On the log, there is no error conditions displayed.
