Description

The Cisco IP Phone 8811 is a business-class IP desk phone from the Cisco IP Phone 8800 Series. It suits small to large enterprises running on-premises Cisco call control, Hosted Collaboration Solution or third-party hosted call control. This SKU is the white colour variant.

The phone has five programmable line keys, a 5-inch 800 x 480 backlit grayscale display and wideband audio with G.722, G.722.2 and Opus support alongside G.711, G.729ab, iLBC and iSAC. A built-in 2-port 10/100/1000 Ethernet switch lets a PC share the phone's LAN connection, with separate 802.1Q VLANs for phone and PC. It is powered by IEEE PoE Class 2 (802.3af, also compatible with 802.3at switches). Handset and headset connect through RJ-9 ports, and an AUX port supports electronic hookswitch control.

It works with Cisco Unified Communications Manager 12.5 and later, Unified CME 10.0 and later, Business Edition 6000 and Hosted Collaboration Solution, and needs an Enhanced User Connect Licence to register to Unified Communications Manager. Optional accessories include the CP-8800-WMK wall-mount kit, the CP-8800-FS spare foot stand and the CP-PWR-CUBE-4 power cube for non-PoE deployments.
