Good to Know
- Battery and charger are separate. Device-only means no battery and no power supply in the box.
- License required. Cisco IP phones need a phone license on your call-control system.
- 8821 vs 8821-EX. The 8821-EX is the hazardous-location version with its own part numbers. This is the standard 8821.
