50
or the IP address (using standard IP addressing format) of the server. The
indicated server must be running TFTP services and have the load file in the
TFTP path. If the load file is not found, the load will not install. The phone will
not be redirected to the TFTP server. If this field is left blank, the phone will use
the designated TFTP server to obtain its load files and upgrades
Recording Tone
This can be used to configure whether the recording tone is enabled or disabled
on the phone. If enabled, the phone mixes the recording tone into both directions
for every call.
Recording Tone Local Volume
This can be used to configure the loudness setting of the recording tone that the
local party hears. This loudness setting applies regardless of the actual device
used for hearing (handset, speakerphone, headset). The loudness setting should be
in the range of 0% to 100%, with 0% being no tone and 100% being at the same
level as the current volume setting. The default value is 100%.
Recording Tone Remote Volume
This can be used to configure the loudness setting of the recording tone that the
remote party hears. The loudness setting should be in the range of 0% to 100%,
with 0% being less than -66dBM and 100% being -4dBM. The default value is -
10dBM or 50%.
Recording Tone Duration
Indicates the length of time in milliseconds for which the recording tone is
inserted in the audio stream. The default for this parameter is set to the value in
the Network locale file for this field. The valid range for this parameter is a value
between 1 and 3000 milliseconds.
Display On When Incoming Call
When the phone is in Screen Save mode this will turn the display on when a call
is ringing.
RTCP
Maintains statistic for audio.
Log Server
Specifies an IP address and port of a remote system where log messages are sent.
Advertise G.722 and iSAC Codecs
Indicates whether Cisco Unified IP Phones will advertise the G.722 codec to
Cisco Unified CallManager. Codec negotiation involves two steps: first, the
phone must advertise the supported codec(s) to Cisco Unified CallManager (not
all endpoints support the same set of codecs). Second, when Cisco Unified
CallManager gets the list of supported codecs from all phones involved in the call
attempt, it chooses a commonly-supported codec based on various factors,
including the region pair setting. Valid values specify Use System Default (this
phone will defer to the setting specified in the enterprise parameter, Advertise
G.722 Codec), Disabled (this phone will not advertise G.722 to Cisco Unified
CallManager) or Enabled (this phone will advertise G.722 to Cisco Unified
CallManager).
Wideband Headset UI Control
Allows users to enable or disable Wideband Headset option on phone UI.
Wideband Headset
Enable or disable the use of a Wideband Headset on the phone. Used in
conjunction with User Control Wideband Headset.
Peer Firmware Sharing
PPID. Enables or disables Peer to Peer image distribution in order to allow a
single phone in a subnet to retrieve an image firmware file then distribute it to its
peers - thus reducing TFTP bandwidth and providing for a faster firmware
upgrade time.
Cisco Discover Protocol (CDP):
Allows administrator to enable or disable Cisco Discovery Protocol (CDP) on the
