DP-9861-K9 Description
The DP-9861-K9 is a Cisco Desk Phone 9800 Series IP phone for reception and attendant desks that handle many lines at once. The phone has a 5-inch 800 x 480 color display, 10 physical line keys with up to 130 lines, dual-band 802.11a/b/g/n/ac Wi-Fi with Bluetooth 5.2, and PoE Class 3 power. The 130-line ceiling applies on CUCM and Webex Dedicated Instance, while Webex Calling and open SIP platforms limit the phone to 16 lines.

Application Scenarios
At a front desk or switchboard position, the operator watches and picks up many lines and colleagues at once from the 10 dedicated hard line keys.
Counters and temporary workpoints with no Ethernet drop can run the phone over dual-band Wi-Fi, with Bluetooth carrying the headset connection.
On unassigned seating in a Webex-integrated office, staff sign in at a free desk and work from their own lines, calendar and call history for the day.

Built in |
DP-9861-K9 and DP-9871-K9 share the same Wi-Fi, Bluetooth 5.2, KEM rules and built-in ThousandEyes Endpoint Agent, and are separated by the input model: DP-9861-K9 has 10 physical line keys on an 800 x 480 display with 130 lines, while DP-9871-K9 runs a 1280 x 720 touchscreen with no line keys and 128 lines. Attendant and reception desks that watch many lines by hard key stay on DP-9861-K9, and users who prefer touch navigation move to DP-9871-K9. Fully cabled desks that need only 6 line keys and 46 lines can use DP-9851-K9, which has no radios, no ThousandEyes agent and one KEM at most. Sites that bar RF transmitters need the No Radio build DP-9861NR-K9.
Ordering Checklist
- Power source: Supply PoE Class 3 (IEEE 802.3af/at) at the access port, or add the regional Cisco Power Adapter 3 PID such as CP-PWR-ADPT-3-NA= or CP-PWR-ADPT-3-EU=. DP-9861-K9 ships without a power supply, so a non-PoE port with no adapter on the order leaves the phone unpowered.
- Call platform: Use Cisco Unified CM 12.5 or later for on-premises registration, plus any device package the CUCM release needs. An older or unpatched CUCM release does not register the phone.
- Key expansion: Add DP-9800-KEM= modules, with one on PoE Class 3 and up to three on Cisco Power Adapter 3. The adapter is a separate line item, so a multi-module build ordered without it has no power path.
- Wall mounting: Add DP-9800-WMK= for the phone, or DP-9800-WMK-88ADP= to reuse an existing 8800 Series wall position; the mount is not part of the phone order.
