5. New Features Descriptions
1. Added the feature of screen saver on T29G, T46G and T48G IP phone.
Description: Each time your phone is idle for a certain amount of time, the screen
saver will automatically start. The screen saver is used to blank the screen or fill it
with moving images or patterns. You can stop the screen saver at any time and
return to the idle screen by pressing a key on the phone. If your phone is idle again
for a specified period of time, the screen saver will start again.
The parameters in the auto provision template are described as follows:
screensaver.wait_time=
screensaver.type =
screensaver.picture_change_interval =
screensaver.clock_move_interval =
screensaver.display_clock_on_upload_picture.enable =
screensaver.upload_url =
screensaver.delete =
To configure the screensaver wait time via phone user interface:
Press Menu -> Basic -> Display -> Screensaver.
YEALINK NETWORK TECHNOLOGY CO.,LTD.
www.yealink.com
To configure the screen saver via web user interface:
Click on Settings -> Preference.
2. Added the feature of power saving on T29G, T46G and T48G IP phone.
Description: The feature of power saving is used to turn off the screen to
conserve energy. The IP phone enters power-saving mode after it has been idle
for a certain period of time. And the IP phone will exit power-saving mode if a
phone event occurs—for example, if the phone has an incoming call or message,
or you press a key on the phone. If the screen saver is enabled on your phone,
power-saving mode will still occur.
The parameters in the auto provision template are described as follows:
features.power_saving.enable =
YEALINK NETWORK TECHNOLOGY CO.,LTD.
www.yealink.com
features.power_saving.office_hour.idle_timeout =
features.power_saving.off_hour.idle_timeout =

features.power_saving.office_hour.Saturday =
features.power_saving.office_hour.Sunday =
To enabled the power saving feature via web user interface:
Click on Settings -> Power Saving.
6. Optimization Descriptions
1. Optimized the feature of Call Park.
Description: You can use call park feature to park a call, and then retrieve the
parked call from another phone (for example, a phone in another office or
conference room). If you configure a call park key for account X, the call park key is
also available for other accounts that are registered on the same sever and on the
same IP phone (the SIP server type of other accounts must be set to Star2Star).
You can configure call park feature under the following three modes: XSI mode,
FAC mode and Transfer mode.

To configure call park feature via web user interface:
Click on Features -> Call Pickup.
