Frequently Asked Questions
The following section describes the FAQs.
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 IP Phone 7841.
Can I use the second line on my Cisco IP Phone 7821 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.
How do I resume a call that is on hold?
To resume a call, press the Hold button, Resume softkey or Line button.
Why does my phone not wake up?
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.
What do four rings in succession 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.
