Cisco Unified Wireless IP Phone 7921G (CP-7921G-W-K9)

The Cisco 7921G is a rugged 802.11a/b/g wireless VoIP handset with a colour display, designed for mobile staff on a Cisco Unified Communications Manager (CUCM) network. Backed by a 12-month Reboot IT warranty and free standard AU shipping.

Key Benefits

• Wireless mobility: 802.11a/b/g Wi-Fi lets staff take calls anywhere with wireless coverage — no desk tether.
• Colour display: A colour screen shows caller ID, directory, and menus for fast on-the-move call handling.
• Enterprise VoIP: Registers to Cisco Unified Communications Manager for full business call features.
• Rugged handset: Built for continuous use in warehouse, retail, and healthcare environments.
• Rechargeable battery: Li-ion battery recharges in a compatible desktop or multi-charger (charger sold separately).
• 12-month Reboot IT warranty: Professionally tested and graded in Melbourne — Australian support since 2001.

Performance in Use

The 7921G is a mobile handset for staff who cannot be tied to a desk — warehouse pickers, retail floor staff, nurses, and facilities teams. On a Cisco CUCM wireless network it behaves like a full desk extension, with directory access, call transfer, and the enterprise features users expect, but with the freedom to roam across the wireless coverage area.

The colour display makes it quick to identify callers and navigate menus on the move, and the ruggedised design stands up to the knocks of a busy shift. The rechargeable Li-ion battery is topped up in a desktop charger or multi-charger between shifts (the CP-DSKCH-7921G desktop charger is a common companion, sold separately).

This handset is best suited to sites already running a Cisco Unified Communications wireless deployment — it is not a standalone SIP phone or a cordless phone for home use.
