from the configuration file, or if the configuration file cannot be
loaded (for example, if the provisioning server is down). To clear a
value from the phone's persistent memory, the parameter may be
set to 'Null' in the configuration file or written again with another
value by the configuration file, HAT or the Admin menus.
SIP specific parameters written to the phone via HAT take effect if
•
the phone is in Version 2 Configuration mode, if the parameter is
not overridden by a value specified in a configuration file.
If either of the configuration files (generic or phone specific)
•
cannot be found, the phone continues to initialize using stored
parameter values (if possible).
The following are behavioral changes that apply to both Version 1
and Version 2 Configuration modes:
•
If using DHCP, and the values for TFTP IP, LOG IP, SNTP IP, SVP
IP, OAI IP, DNS IP, or DNS Domain are not received via DHCP,
the phone will use the value saved in the phone (if any) from
previous configurations via HAT, menus, or configuration files.
If all specified lines that have proxies fail to register and there are
•
no lines defined without proxies, the phone will reboot (with "N
of M lines unregistered" message).
SIP code no longer uses the SIP TFTP IP address to get
configuration files, it now uses the same address for downloading
files via either HTTP or TFTP.
The HTTP Server Address takes precedence over the TFTP Server
address. The TFTP Server address will only be used if an HTTP
Server address is not provided or the configuration files cannot be
found at the HTTP Server address.
