- NO — PC port is disabled.
• LLDP_ENABLE [YES | NO] —
- YES – 802.1ab (LLDP) is enabled.
- NO – 802.1ab (LLDP) is disabled (default).
• HTTP_RETRY_NUMBER [x] — This parameter configures the number of times the IP
Deskphone attempts to contact the server when an HTTP 503 (server is unavailable) response
is received. The IP Deskphone stops trying to connect to the server after
HTTP_RETRY_NUMBER unsuccessful attempts have been made, or if any other response
except HTTP 503 is received from the server.
x = positive integer. The default is 5.
If HTTP_RETRY_NUMBER is not specified in the Device Configuration file, the default number
of attempts is applied.
If HTTP_RETRY_NUMBER is set to 0 in the Device Configuration file, the IP Deskphone
performs HTTP retries continuously until it receives a response other than HTTP 503. If the
HTTP_RETRY_NUMBER is configured as a negative value, the default number of attempts is
applied.
• DHCP_NUMBER_OF_RETRIES [x] — This parameter configures the number of times the IP
Deskphone attempts to contact the DHCP server.
The default value is 4.
- minimum value is 1
- maximum value is 10
If the value defined in the System Configuration file is incorrect, the default value is used.
• DHCP_INITIAL_TIMEOUT [x] — This parameter configures the initial time interval between
attempts by the IP Deskphone to contact the DHCP server.
The default value is 4 seconds.
If the DHCP server does not respond, the IP Deskphone sends several requests one after
another in different timeout intervals, based on the formula
timeout[i]=2* timeout[i-1] +- 1second
where “i” is the number of retries and timeout[0]= DHCP_INITIAL_TIMEOUT. The maximum
timeout between Discovery requests cannot be greater than 64 seconds. If the value of the
next timeout becomes greater than 64 seconds, the DHCP client stops increasing the timeout
interval and keeps the timeout value of 64 seconds.
- minimum value is 4 seconds
- maximum value – 10 seconds
If the value defined in the System Configuration file is incorrect, the default value is used.
• DHCP_UNTAG_ENABLED [YES | NO] — When this parameter is enabled, the IP Deskphone
attempts to obtain an IP address in a VLAN (DHCP discovery frames are tagged), and the
DHCP server is unreachable, then after the pre-defined number of Discovery attempts the IP
