Product Overview
The Cisco Unified IP Phone 6901 is a single-line endpoint delivering cost-effective access to Cisco Unified Communications. Designed with a trimline-like low profile, the Cisco Unified IP Phone 6901 is an ideal solution for lobbies, hallways, elevators, hotel bathrooms, or other settings that have an occasional need for voice communications services.
The Cisco Unified IP Phone 6901 supports two incoming calls with call-waiting service. Fixed feature keys provide one-touch access to Hold, Redial, and Call waiting. Transfer and Conference can be supported by using the hook-switch similar to that of traditional analog phones.
The Cisco Unified IP Phone 6901 offers personalization, with the choice of two colors (charcoal and arctic white) and two handset style options (slimline and standard).
The Cisco Unified IP Phone 6901 is an earth-friendly solution. As with the other Cisco Unified IP Phone 6900 Series endpoints, the Cisco Unified IP Phone 6901 takes advantage of reground and recyclable plastics for a more earth-responsible solution.
