Cisco CP-7841-K9= 7800 Series Voip Phone (Power Supply Not Included), black

Missing power adaptor for phone

This phone is not compatible with VOIP , and not configure with our interface As this handset is missing its users button-icon from there you can configure handset. I did tried so hard, left messages, BUT SELLER NEVER responded. Had to return this item.

I just got this in my office Sept 2019. I'm surprised at how hard it is to use features. The "Recent" Call list does not utilize the screen well. I can see the time/date, but there is no room for the phone number. To get the phone number, I need to click a button to see a differnt screen, from which, I cannot advance to the next call in the list, I need to press more buttons to go back, and select, and then see details... it's too much of a pain and essentially useless. Also useless is the SpeedDial Function. 1st of all, there is no SpeedDial function on the phone, it's all stored on a back-end server somewhere. Second, you can't just hit SpeedDial+1, you have to click into a menu, put in a PIN number and then scroll through... so useless. I hate this phone.

All fine!

Firmware on these phones is from 2013 and not upgradable to current software versions. These phones are "new" but have been sitting in a warehouse somewhere for years. This should have been stated in the description. I'll be returning my order.
