Cisco Desk Phone 9800 Series 9851

The Cisco DP-9851 is a corded VoIP desk phone with a 3.7 inch LCD and six programmable lines. It suits office workers who need a single device for calling, meetings and desk reservations across multiple cloud platforms.

Check PoE and call platform before ordering

Verify that your network switch provides Power over Ethernet because the phone draws power through its two RJ-45 ports. Confirm that your call control system supports Cisco Unified Communications Manager, Webex Calling, Broadworks or compatible third-party SIP platforms.

Ideal for unified workspaces, not for analogue lines

This phone fits organisations consolidating desk hardware into one secure endpoint for hybrid work. Buyers who need analogue or ISDN connectivity, or who require a colour touchscreen, should look at alternative models.

Questions about this item

Does the DP-9851-K9= include a power supply or must I buy one separately?

The phone has two PoE network ports so it can receive power and data over a single Ethernet cable; no separate power supply is required.

How do I decide between the 9800 series models when they all share the same PhoneOS software?

Choose the 9851 for its 3.7 inch LCD and six-line capacity; other 9800 models differ in screen size and line count.

What does the six-line specification mean for daily call handling?

It allows six simultaneous call appearances so you can manage multiple conversations, hold lines, or shared extensions without additional hardware.
