Cisco CP-8841-3PCC-K9 SIP VoIP Phone for Third Party Call Control

The phone came in black and does not include the power supply. The description says to purchase the CP-PWR-CUBE-3= but that's the wrong power supply. Does not fit! You need to purchase the one with Cisco Part Number 341-0330-02 which I think is the CP-PWR-CUBE-4. Seller needs to update their product description page.

DO NOT BUY THIS PHONE! I purchased this exact phone in February 2025 and had to hire an IT company to activate and program the phone. It randomly stopped working on July 23,2025 and I called company to assist and they said they couldn't help me due to me not saving the box with an activation code on it. I did not think that the box needed to be saved for the lifetime of the phone but it did. I purchased another phone on July 24, 2025 and it was shipped with no activation code and company is no help at all. At the price that it is sold for, they should be willing to assist with setup. DO NOT PURCHASE THIS PHONE!

Very nice product and service.

3PCC means that the image you are viewing is NOT what you get. Cisco has illegally and with no concern to the end user willfully removed all color backgrounds and menus advertised with this phone in an effort to monopolize business and hurt competition. If your 3rd party provider uses anything other than Cisco unified (like broadsoft) the features have been removed and the hardware is does not function as advertised even on their own website. This was deemed illegal by the Supreme Court and even in Europe when Microsoft tried to do the same thing twice. Remember Netscape. Remember Java. Remember the billions they paid out for violating Anti-trust and showing noncompetitive behavior. Watch for the class action on this one folks

Phone arrived in new condition. However, the picture shows the phone in white, which is what I needed. Instead I got the phone in black.

If you need this for a CUCM system, this is not the phone for you. 3PCC phones are for third-party call control systems. Converting a 3PCC phone to a regular CUCM phone is very difficult, maybe impossible.

Highly unreliable phone - will regularly shut down and restart every 45 to 50 minutes, ending your call. Wish I could return it given the outlandish price

If you're buying this for a CUCM environment, beware, you can't get rid of the universal (ironic) code to use it with CUCM. We've tried everything we can think of to no avail. It's now a paperweight. Shipping, delivery etc were all excellent.

Does not work, waste of money will be returning.
