Up to six people around the table, a 3.1-inch 248×120 backlit screen, full 360° voice pickup with Yealink Noise Proof, built-in Wi-Fi 5 and Bluetooth 4.0, USB port for desktop softphone use, PoE-capable. The CP920 is the conference phone we put in huddle rooms and smaller meeting spaces.
The CP920 is Yealink's small-room conference phone — designed for six people max around a typical 6-foot table. The 360° microphone array picks up voice cleanly within about a 20-foot radius, and Yealink's Noise Proof technology suppresses HVAC, keyboard typing, and other ambient noise without cutting human speech. For huddle rooms and small meeting spaces, this is the right tier.
Where the wireless features earn their money: built-in Wi-Fi 5 means you can drop the CP920 in a conference room without pulling ethernet, and Bluetooth lets a presenter pair their laptop or phone to use the CP920 as the audio device for a Zoom or Teams call running on their machine. The USB port does the same thing for wired softphone setups. One device covers both standalone SIP conference calling AND being the audio for laptop-based calls.
Where to step up: the CP925 is $50 more and adds a 4-inch touchscreen for easier navigation. The CP965 is the boardroom version with expandable mics for larger rooms. The CP935W is a wireless DECT alternative for spaces without ethernet or Wi-Fi.
Where to skip it: any room with more than 6 people regularly. The mic range is the limit — you can squeeze 8 people around if they all lean in, but voice quality degrades for participants further from the center. For 8+ rooms, go straight to the CP965 with expansion microphones.

Plug the CP920 into PoE and ethernet. About a minute later it has registered to your extension. Same auto-provisioning flow as every other supported phone — no SIP credentials to type, no firmware to chase.
Boot, fetch config from our provisioning server, register, ready. About one minute on a normal connection.
Multi-line per phone. Each line key has a dual-color LED for status at a glance.
Programmable mapped from the voip.army portal — BLF, paging, parking, transfer destinations.
Bringing your own? Send us the MAC, factory-reset, plug in. No charge to add it to the fleet.
Standard PoE — any 802.3af-compliant switch from the last 15 years powers the phone without an adapter.
Tested against every Yealink firmware release for CP920. We catch regressions before they reach your fleet.
