Cisco 7811 IP Phone for desk workers

The Cisco 7811 is a monochrome VoIP handset designed for single-line use in office environments. It provides caller ID and a built-in speakerphone for everyday business calls. The charcoal finish suits professional workspaces.

Check PoE and network cabling before ordering

Your switch must supply Power over Ethernet because the phone draws power through its two RJ-45 network ports. Confirm that DHCP, SRTP, CDP and LDAP services are available on the network. A single Cat5e or better cable run is required for each desk.

Wall-mountable design saves desk space

The unit can be fixed to a wall, freeing the desktop for other equipment. Two network ports allow daisy-chaining a PC through the phone so only one wall jack is needed. The handset weighs 2.4 units and fits standard VoIP deployments.

Questions about this item

Does the Cisco 7811 IP phone include the Ethernet cable and power supply, or must they be purchased separately?

The phone ships with a cable and supports Power over Ethernet through its two RJ-45 ports, so a separate power supply is not required when connected to a PoE switch.

Should I choose the CP-7811-K9= or the CP-6825-3PCCEK9 for a desk-based VoIP deployment?

The CP-7811-K9= is a wired desk phone with dual network ports and PoE, while the CP-6825-3PCCEK9 is a DECT handset intended for mobile use, making the 7811 the desk-appropriate choice.

What does the single line appearance on the 7811 mean for daily call handling?

The phone provides one programmable line key, allowing you to place, hold and transfer a single active call at a time on the monochrome display.
