Chapter 4 Configuring Settings on the Cisco Unified IP Phone
Device Configuration Menu
Network Configuration Menu
The Network Configuration menu displays device-specific network configuration settings on the phone.
Table 4-20 describes the options in this menu.
Note The phone also has a Network Configuration menu that you access directly from the Settings menu. For
information about the options on that menu, see Network Configuration Menu, page 4-6.
Table 4-20 Network Configuration Menu Options
Option Description To Change
Load Server Used to optimize installation time for phone firmware upgrades
and offload the WAN by storing images locally, negating the
need to traverse the WAN link for each phone's upgrade.
You can set the Load Server to another TFTP server IP address
or name (other than the TFTP Server 1 or TFTP Server 2) from
which the phone firmware can be retrieved for phone upgrades.
When the Load Server option is set, the phone contacts the
designated server for the firmware upgrade.
Note The Load Server option allows you to specify an
alternate TFTP server for phone upgrades only. The
phone continues to use TFTP Server 1 or TFTP Server 2
to obtain configuration files. The Load Server option
does not provide management of the process and of the
files, such as file transfer, compression, deletion, and so
on.
From Cisco Unified Communications
Manager Administration, choose Device
> Phone > Phone Configuration.
RTP Control
Protocol
Indicates whether the phone supports the Real-Time Control
Protocol (RTCP). Settings include:
• Enabled
• Disabled—default
If this feature is disabled, several call statistic values display as
0. For additional information, see the following sections:
• Call Statistics Screen, page 7-12
• Streaming Statistics, page 8-11
From Cisco Unified Communications
Manager Administration, choose Device
> Phone > Phone Configuration.
CDP: PC Port Indicates whether CDP is supported on the PC port (default is
enabled).
Enable CDP on the PC port when Cisco VT Advantage/Unified
Video Advantage (CVTA) is connected to the PC port. CVTA
does not work without CDP interaction with the phone.
Note When CDP is disabled in Cisco Unified
Communications Manager, a warning is displayed,
indicating that disabling CDP on the PC port prevents
CVTA from working.
Note The current PC and switch port CDP values are shown on
the Settings menu.
Use Cisco Unified
Communications Manager
Administration, and choose Device >
Phone.
