Q&A (CP-8841-K9)

Why can't I see all the active calls on my phone?

When there are more calls than available session buttons on the phone, you can scroll to see them. Calls are sorted from oldest to newest, with the oldest call at the top of the list.

How do I redirect an incoming call when I am on a call?

To redirect an incoming (ringing) call while on another call, highlight the incoming call, and then press Decline. Otherwise press Decline to redirect the current, active call.

How do I silence a ringing call, if I'm on a call?

You can silence the incoming (ringing) call. Press Volume down once, and then let the incoming call go to the target number (voice mail or predetermined number set up the system administrator).

What is the difference between the buttons on the left and those on the right of the screen?

Your phone has feature buttons on the left and call session buttons on the right. Use the feature buttons to access features (such as speed dial) or select a phone line. Use call session buttons to perform call-related tasks, such as making a new call, resuming a held call, or checking your voicemail. The positions of the session buttons and feature buttons can be reversed on phones that use a locale with a right-to-left reading orientation, such as Hebrew and Arabic.

Why do the softkeys keep changing?

Softkeys act on the selected (highlighted) call or menu item only. The softkeys that display depend on the call or item you have selected.

What is the best way to look at calls when I have a shared line or multiple lines?

If you have a shared line or multiple lines, it is recommended that you use the All Calls feature to view calls. When you press the All Calls button (on the left), all calls for all your lines are listed on the phone screen in chronological order (oldest first). If you do not have an All Calls button, contact your system administrator to set up this feature. Your administrator can also set up your primary line key to act the same as the All Calls button.

What should I do if I accidentally press a button while on a call?

If you are on a call and press a button for another line, your line view will change. Your current call disappears from view and calls for the newly selected line are displayed. To redisplay the call you are on, select the line that it is on, press All Calls, or, press the Primary line key if it is set up by your administrator to display all calls.

What does the Swap softkey do?

The Swap softkey allows you to toggle between two calls before completing the transfer or creating a conference. This allows you to consult privately with the party or parties on each call before combining the calls into a conference.

Can I cancel a conference or transfer procedure after I have started it?

Yes, before completing a conference or transfer, you can press Release or Cancel to cancel it.

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 wakes up at the time your system administrator configured. You can press the Select button to wake your phone up. Contact your system administrator to have the sleep and wake up times changed.

What happens to video when I put a call on hold?

Video transmission is blocked until you resume the call.

Nice looking phone, setup takes time.

Very good phones, these look very polished and have been received very well. They were a bit difficult to get working with our VPN setup but they seem reliable once the settings were tweaked.

Great Phone at a great price. This is cheaper than the 8841 that we typically purchase from our Cisco Partner. Don't let the name scare you off.
