Description

The Cisco IP Phone 8841 is a business-class desk phone from the Cisco IP Phone 8800 Series, built for small to large enterprises running on-premises or hosted Cisco call control. This SKU is the Charcoal model running Cisco Unified Communications Manager firmware, not the multiplatform 3PCC version.

It has a 5-inch 800 x 480 WVGA backlit display, five programmable line keys, wideband audio with a full-duplex speakerphone, and an analog RJ-9 headset port plus an AUX port for an electronic hookswitch. An internal 2-port 10/100/1000BASE-T switch lets a PC share the phone's network connection. Power comes from IEEE 802.3af/802.3at PoE Class 2, with an input rating of 0.917 A at 48 V DC.

It requires an Enhanced User Connect Licence to register with Cisco Unified Communications Manager, and it works with Unified CME 10.0 and later, Business Edition 6000 and Hosted Collaboration Solution. Compatible accessories include the CP-8800-WMK= wall-mount kit, CP-8800-FS= foot stand, CP-8800-S-BEZEL= silver bezel, CP-DX-HS= spare handset and CP-PWR-CUBE-4= power cube.
