Why don’t I see the icons shown in the documentation on my phone screen?
Many of the phone screen icons are applicable only to the Cisco Unified IP Phones 6941 and 6945.
Can I use the second line on my Cisco Unified IP Phone 6921 as a feature button?
Yes. If you do not require two phone lines, your system administrator can set up a feature on your second line.
When I put a call on hold by pushing the Hold button, why doesn’t pushing the button again resume the call?
The Hold button is used only to put a call on hold. To resume a call, press the Resume softkey or the flashing green line button.
Why does my phone not work ("wake up"), when it worked before?
If your system administrator has set up your phone for EnergyWise, the phone may be sleeping (powered down). Your system administrator sets your phone to sleep at a certain time and wake (power up) at a certain time. Your phone will wake up at the time set by your system administrator. You can press the Select button to wake your phone up. See your system administrator to have the sleep and wake up times changed.
My phone played the ringtone four times in succession, but there is no call. What does this mean?
The phone is notifying you that your phone will power down (sleep) soon to conserve energy (the EnergyWise feature). Your system administrator sets your phone to sleep at a certain time and wake (power up) at a certain time. Your phone will wake up at the time set by your system administrator. See your system administrator to have the sleep and wake up times changed.
What do I do if my phone displays the message Security Error?
Your phone firmware has identified an internal error. Try unplugging the phone from the power source, wait one minute, and then plug the phone back in. If the message persists, contact your system administrator.

Cleaning Cisco Unified IP Phone
To clean your Cisco Unified IP Phone, use only a dry soft cloth to gently wipe the phone and the phone screen. Do not apply liquids or powders directly on the phone. As with all non-weather-proof electronics, liquids and powders can damage the components and cause failures.
When the phone is in sleep mode, the touchscreen is blank and the Select button is not lit. When the phone is in this condition, you can clean the screen, as long as you know that the phone will remain asleep until after you finish cleaning. If the phone is likely to wake up during cleaning, wake it up or wait until it is awake before following the preceding cleaning instructions.
