When you are upgrading phone software using the Web Configuration Utility, the phone is unable to
connect to the Polycom Hosted Server.
Occasionally, the phone is unable to connect to the Polycom Hosted Server because:

The Polycom Hosted Server is temporarily unavailable.

There isn't any software upgrade information for the phone to receive.

The network configuration is preventing the phone from connecting to the Polycom Hosted Server.
