Feature Availability
Depending on your phone system configuration, features included in this Phone Guide might not be available
to you or might work differently on your phone. Contact your support desk or system administrator for
information about feature operation or availability.
SIP and SCCP Signaling Protocols
Your phone can be configured to work with one of two signaling protocols: SIP (Session Initiation Protocol)
or SCCP (Skinny Call Control Protocol). Your system administrator determines this configuration.
Phone features can vary depending on the protocol. This Phone Guide indicates which features are
protocol-specific. To learn which protocol your phone is using, you can contact your system administrator or
you can choose > Model Information > Call Control Protocol on your phone.
Energy Savings
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 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 off
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 schedule 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.
For more information about EnergyWise and your phone, contact your system administrator.
