Configuration and look at the Communications Manager 1–4 options. (See

If none of the Cisco Unified Communications Manager options contain IP addresses or show Active
or Standby, the phone is not properly registered with Cisco Unified Communications Manager. See
the

for
tips on resolving this problem.
Cisco Communications Manager and TFTP Services are not Running
If the Cisco CallManager or TFTP services are not running, phones might not be able to start up properly.
However, in such situations, it is likely that you are experiencing a system-wide failure and that other
phones and devices are unable to start up properly.
If the Cisco CallManager service is not running, all devices on the network that rely on it to make phone
calls will be affected. If the TFTP service is not running, many devices will not be able to start up
successfully.

The Service Status symbol changes from a square to an arrow.
