Automated Boot Code Update
Information about the automatic update of endpoint boot code is included in this guide for the
following reasons:
You may be unaware that the update is occurring.
Interruption of power to the endpoint during the download causes the endpoint to be
inoperable and unrecoverable.
A Model 8620/8622, or 8662 endpoint with v2.0.0 or later firmware uses a TFTP server to
update a crucial internal boot code. In any of the following situations, the endpoint checks its
configuration file against a corresponding file on the TFTP server:
On startup
On command
On periodic timeout
If the endpoint detects new parameters during this check, it automatically initiates the
boot update procedure to download new boot code. However, the download is delayed
if a call is in progress or music on hold is enabled. The endpoint display changes to
alert you that the update is in progress...
Displays
Some IP and SIP endpoints provide a Liquid Crystal Display (LCD) that shows caller and fea-
ture information.
Six-Line Display
Some endpoints, like the Model 8660 and 8662 endpoints have a six-line LCD. Each line has
16 characters. The top two lines are for standard call information and show the same displays
as other display phones. The remaining four lines are used for displaying feature-related menus
that change with the function being performed by the endpoint (intercom call, outside call, pro-
gramming, etc.). These lines have menu selection buttons on both sides (eight buttons) that are
used for menu features. When there are two prompts on a line, like PREVIOUS and NEXT, the
button next to the word is the one that will select that feature. When there is only one prompt
on a line, like DO NOT DISTURB, then pressing the button on either side of the prompt will
select it.
There is a system-wide flag, called “Alter-
nate Keyset Menu Displays,” that deter-
mines the display that users see during an
outside call. In the default state, the display
shows the following menu with Transfer-
To-Hold on the first menu and Flash on the
“More...” menu:
CAUTION
If, during the boot code download, electrical current to the endpoint is interrupted (e.g.,
through disconnection or a power outage), the endpoint becomes inoperable and cannot be
recovered. In that event, the endpoint must be returned to Inter-Tel for repair.
NOTE
For endpoints operating in SIP mode, voice mail displays are not supported;
however, the user will still receive audio prompts.
