2. Manually reboot the phone so that it will download the new key. The
phone will automatically reboot a second time to use the new key.
At this point, the phone expects all encrypted configuration files on the
boot server to use the new key and it will continue to reboot until this is
the case. The files on the server must be updated to the new key or they
must be made available in unencrypted format. Updating to the new key
requires decrypting the file with the old key, then encrypting it with the
new key.
Note that configuration files, contact directory files and configuration
override files may all need to be updated if they were already encrypted.
In the case of configuration override files, they can be deleted from the
boot server so that the phone will replace them when it successfully boots.
Adding a Background Logo
This section provides instructions on how to add a background logo to all
SoundPoint IP phones in your organization. You must be running at least
BootROM 2.x.x and SIP 1.x.x. One bitmap file is required for each model, but
SoundPoint IP 301 phones do not support bitmap logos.
Logos smaller than described in the table above are acceptable, but larger
logos may be truncated or interfere with other areas of the user interface.
