Page 86 Automated Boot Code Update
Because IP endpoints connected on P2P calls do not use Inter-Tel 5000 resources, users cannot
access Agent Help, Record-A-Call, and Station Monitor features.
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 time-out
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.
NOTICE
Passing real-time streaming data, such as audio, through encrypted virtual private net-
works (VPN) may significantly impact the network performance, router and firewall func-
tionality, and audio quality.
NOTICE
Severe endpoint damage possible. 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.
