Application Scenarios
On an assigned office desk, daily call handling, directory search and calendar interaction run on the 1280 x 720 touchscreen instead of a field of line buttons.
Shared seating areas on Webex-integrated call control let staff sign in at any station through hot desking, and the phone takes on their profile for the day.
Reception counters, lobby desks and temporary workstations without a wired LAN drop can register to call control over dual-band 802.11ac Wi-Fi.

DP-9871-K9 and DP-9861-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-9871-K9 runs a 1280 x 720 touchscreen with no line keys and 128 lines, while DP-9861-K9 has 10 physical line keys on an 800 x 480 display with 130 lines. Desks that rely on hard line keys, or attendant roles near the 130-line ceiling, move to DP-9861-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-9871NR-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-9871-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.
