### ⭐ THESE PHONES ARE LOCKED AND CAN NOT BE ACTIVATED. STAY AWAY! YOU'VE BEEN WARNED
*by B***E on June 2, 2023*

IT ASK FOR A CODE, AND PER THE TECH AT RINGCENTRAL, IF IT IS ASKING FOR A CODE, THIS MEANS THE PHONE IS LOCKED TO A COMPANY/CARRIER AND CAN NOT BE ACTIVATED ELSEWHERE.

### ⭐⭐⭐⭐ CUCM Compatible. Not MPP/SIP without rigorous Set-Up
*by J***S on June 19, 2025*

For those customers who are looking to buy a 8851 Cisco phone please be aware that many of the phones ordered are CUCM phones meaning that they only work with Cisco Software, these phones will not work with a aplication like FreePBX or 3CX or similar pbx softwares. Though if you know people who are in the IT industry who know how to set these up do not buy. Overall the quality of the phone is okay it is in great condition. You have been warned... Unless you know what you are doing.
