Fixes for the most common Yealink CP925 problems, from the quickest checks to when to contact Yealink. Start at the top: most issues are a setting, a cable or firmware.
What the CP925 has
Check the problem against what this model actually has:
- Display: 4-inch multi-touch, 480 x 800
- Microphones: 6-mic array for voice pickup + 1 for noise cancellation
- Audio: Optimal HD audio, full duplex, Yealink Noise Proof Technology
- Wireless: Wi-Fi 2.4/5 GHz (802.11a/b/g/n), Bluetooth 4.2
- Power: Power over Ethernet
- Expansion: Optional Bluetooth wireless microphones
Quick checks
- Restart it: unplug the network cable for 30 seconds, then reconnect.
- Reconnect the cables, using the ones that came in the box.
- Check that the CP925 is selected as the microphone and speaker in Teams, Zoom or Meet.
- Update the firmware. How
No sound or people can't hear you
- Check the device isn't muted (look for a red mute light).
- In the meeting app, select the CP925 as both microphone and speaker.
- Check the volume on the device and on the computer.
- Move laptops and their fans away from the microphones.
Echo or feedback
- Make sure only one microphone and one speaker are active in the room: mute laptops that also joined the meeting.
- Don't run the room's audio through both the device and the TV speakers at the same time.
- Hard, bare rooms reflect sound. Rugs, curtains or acoustic panels reduce echo a lot.
- Update firmware: echo cancellation improvements often come in updates.
Keeps disconnecting or drops out
- Use wired Ethernet rather than Wi-Fi, and check the switch port for errors.
- Update firmware and the meeting app.
Won't turn on
- Check the switch port supplies PoE and has enough power budget left.
- Try a known-good cable and a PoE injector to rule out the switch.
- If it starts and then restarts, the port may not supply enough power.
