If you are using DNS to refer to the TFTP server or to
Cisco Unified CallManager, you must ensure that you have specified a DNS
server. Verify this setting by pressing the Settings button on the phone, choosing
Network Configuration, and scrolling to the DNS Server 1 option. You should
also verify that there is a CNAME entry in the DNS server for the TFTP server
and for the Cisco Unified CallManager system.
You must also ensure that DNS is configured to do reverse look-ups.
On the Cisco Unified IP Phone, press the Settings button, choose Network
Configuration, and look at the CallManager 1–5 options. The Cisco Unified IP
Phone attempts to open a TCP connection to all the Cisco Unified CallManager
servers that are part of the assigned Cisco Unified CallManager group. If none of
these options contain IP addresses or show Active or Standby, the phone is not
properly registered with Cisco Unified CallManager. See the
Phone with Cisco Unified CallManager" section on page 9-8
this problem.
If the Cisco Unified CallManager or TFTP services are not running, phones may
not be able to start up properly. However, in such a situation, 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 Unified 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.
To start a service, follow these steps:
Procedure
From Cisco Unified CallManager Administration, choose Application >
Cisco CallManager Serviceability.
Choose Tools > Control Center.
