Power Saving Configuration
You can enable or disable power saving, and set the different idle timeout for office hours and off hours.
l
Office Hour: specify the start time and end time of the day’s office hour. You can change the office hours to avoid
affecting your work.
l
Idle Timeout: specify the period of time before the IP phone enters the power-saving mode.
You can specify the following three types of idle timeout:
l
Office Hours Idle TimeOut: specify the idle timeout for office hours.
l
Off Hours Idle TimeOut: specify the idle timeout for non-office hours.
l
User Input Extension Idle TimeOut: specify the idle timeout that applies after you use the IP phone (for example,
press a key on the phone or pick up/hang up the handset).
By default, the Office Hours Idle Timeout is much longer than the Off Hours Idle TimeOut. If you use the IP phone,
the idle timeout that applies (User Input Extension Idle Timeout or Office Hours/Off Hours Idle TimeOut) is the
timeout with the highest value.
If the phone has an incoming call or new message, the User Input Extension Idle TimeOut is ignored.
Tip: You can choose to set a higher User Input Extension Idle TimeOut than the Office Hours Idle TimeOut and Off Hours Idle
TimeOut so that the phone does not enter the power-saving mode too often after you use the phone.
The following table lists the parameters you can use to configure power saving.
