Rated 4 out of 5 stars.
If you're running a Mitel phone system in your office, this Superset 4025 is a solid, reliable workhorse.

The dark charcoal gray finish looks professional on any desk, and that backlit display makes it easy to see calls even in low light.

You get 13 programmable keys that you can customize for speed dial or features, plus 10 fixed-function keys for common tasks.
The built-in speakerphone works great for hands-free calls, and caller display shows you who's calling before you even pick up.

This thing only works on digital extension lines that have been programmed for Superset 4025 models, so it's perfect for businesses using SX-200 ML/EL or SX-2000 systems.

The 14 personal keys with status indicators let you see line conditions at a glance.
It's not fancy like the latest VoIP phones, but it's incredibly reliable and does exactly what an office phone should do - make clear calls day in and day out without any fuss.
