Combining the high-def Video conferencing from the 8845 and all the connection options from the 8861, this flagship phone works well everywhere. It’s great for open workspaces, large conference rooms, executive offices, and actively mobile users within a campus.
The 8865 is meant to be a successor to the 9951/9971 models. The only difference between the 8865 and the 8845 is here we see more modular compatibility. It has wi-fi and the ability to add KEM accessories or any other hard wired connection standard to the 8861.
Considering the moderate price difference between this phone and the 8845, this phone likely offers superior value.
