Your phone supports the Cisco EnergyWise program. Your system administrator sets up sleep (power down) and wake (power up) times for your phone to save energy.
Ten minutes before the scheduled sleep time, if the audible alert is enabled by your system administrator, you hear your ringtone play. The ringtone plays according to the following schedule:
At 10 minutes before power down, the ringtone plays four times
At 7 minutes before power down, the ringtone plays four times
At 4 minutes before power down, the ringtone plays four times
At 30 seconds before power down, the ringtone plays 15 times or until the phone powers down
If your phone is inactive (idle) at the sleep time, you see a message to remind you that your phone is going to power down. To keep the phone active, press any key on the phone. If you do not press any key, your phone powers down.
If your phone is active (for example, on a call), your phone waits until it has been inactive for a period of time before informing you of the pending power shutdown. Before the shutdown happens, you see a message to remind you that your phone is going to power down.
At the scheduled time, your phone powers up. To wake up the phone before the scheduled time, contact your administrator.
Wake and sleep times are also linked to the configured days that you normally work. If your requirements change (for example, your work hours or work days change), see your system administrator to have your phone reconfigured.
