Cisco Discover Protocol (CDP) This parameter allows the administrator to enable or disable Cisco Discovery
Protocol (CDP).
SSH Access This parameter specifies whether the phone will accept SSH connections.
Disabling SSH Access will prevent access to the phone via SSH.
Ring Locale This parameter specified the ring cadence. The phone has distinctive ring for On-
net/Off-net or line based, but its ring cadence is fixed, and it is based on US
standard only. Ring cadence in US standard is opposite to Japan standard. To
support Japan ring cadence, the ring cadence should be configurable according to
Ring Locale.
TLS Resumption Timer
This parameter specifies the maximum session resumption time allowed. The
current TLS session to support TLS session resumption is HTTPS client. The
HTTPS client sessions support configurable session resumption timer. If the
value is set to 0, TLS session resumption will be disabled.
FIPS Mode This parameter specifies if FIPS mode is enabled or disabled.
Record Call Log From Shared Line This parameter specifies whether to record call log from shared line or not.
Minimum Ring Volume This parameter controls the minimum ring volume on the phone. This value is set
by the administrator, and can not be changed by an end user. The end user can
increase the ring volume, but may not decrease the ring volume below the level
defined. The minimum ring volume range is from 0 to 15, with 0 (silent) being
the default value.
Load Server
This parameter specifies that the phone will use an alternative server to obtain
firmware loads and upgrades, rather than the defined TFTP server. This option
enables you to indicate a local server to be used for firmware upgrades, which
can assist in reducing install times, particularly for upgrades over a WAN. Enter
the hostname 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.
IPv6 Load Server
This parameter specifies that the phone will use an alternative IPv6 server to
obtain firmware loads and upgrades, rather than the defined TFTP server. This
option enables you to indicate a local IPv6 server to be used for firmware
upgrades, which can assist in reducing install times, particularly for upgrades
over a WAN. Enter the hostname or the IPv6 address (using standard IPv6
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.
WLAN SCEP Server
This parameter specifies the SCEP Server the phone will use to obtain certificates
for WLAN authentication. Enter the hostname or the IP address (using standard
IP addressing format) of the server.
WLAN Root CA Fingerprint
(SHA256 or SHA1) This parameter specifies the SHA256 or SHA1 fingerprint of the Root CA to use
for validation during the SCEP process when issuing certificates for WLAN
authentication. It is recommended to utilize the SHA256 fingerprint, which can
be obtained via OpenSSL (e.g. openssl x509 -in rootca.cer -noout -sha256 -
fingerprint) or using a Web Browser to inspect the certificate details. Enter the 64
