Description

The Cisco IP Phone 8851 is a five-line desk phone in the Cisco IP Phone 8800 Series, built for office and enterprise users who work on hosted or third-party SIP PBX and UCaaS platforms. It suits staff who juggle several calls at once and want Bluetooth or USB headset options.

This 3PCC SKU runs Multiplatform Phone (MPP) firmware, so it registers directly to third-party SIP call-control platforms and supports up to 10 SIP registrations. It has a 5-inch WVGA (800 x 480) backlit colour display, five programmable line keys, and a 2-port 10/100/1000BASE-T switch with PC pass-through. Wideband G.722 audio runs across the handset, speakerphone and headset. Headset connections include RJ-9, an auxiliary port, USB and Bluetooth 3.0 EDR Class 1, and the side USB port provides up to 2.5 W for charging a smartphone. Power is supplied over IEEE 802.3af/at PoE. No Cisco call-control licence is required, and any user or device licensing is set by your SIP platform.

It is compatible with the CP-8800-A-KEM-3PC= Key Expansion Module (MPP firmware 11.2.3 or later), the Cisco Power Cube 4 and Cisco headsets. A wall-mount option and a two-position foot stand are available.
