3. Notes
3.1 Upgrading
This section lists the changes that should be made to configuration files when using the
centralized (boot server) provisioning model. For general guidelines, see the Updating and
Rebooting information in Section 4.3 of the Administrator Guide.
3.1.1 From Version 2.2.1 to 2.2.2
3.1.1.1 Mandatory Changes
• None.
3.1.1.2 Optional Changes
• TCP Keep-Alive message when using TLS
Configure the tcpIpApp.KeepAlive parameters as detailed in Section 2.1.4 if using
TLS and there is a risk of the TCP connection being improperly terminated.
• Read-only Contact Directory
If it is desired to centrally manage the phones directory, the user can be restricted
from making any changes. To enable this capability set dir.local.read-only = “1”
• Disable Presence (MyStat and Buddies) soft-keys when using the Presence
feature signalling
Some call servers use the phones ‘Presence’ feature for controlling BLF capability
but don’t implement the full suite of Presence options. To avoid giving the user
visibility to this setting, the idle soft-keys may be removed from the phone UI by
setting pres.idleSoftKeys=”0”

3.1.2.1 Mandatory Changes

3.1.3.1 Mandatory Changes
• New configuration file settings for audio
The entire “voice” section in the latest sip.cfg must be used to ensure good audio
quality.
• New configuration file settings for indicators
The entire “indicators” section in the latest sip.cfg must be used to ensure correct
icons on the display.
