ringing, or to adjust the volume of engaged audio device (handset, speakerphone or headset)
when there is an active call in progress.
Why do I get poor sound quality during a call?
If you have poor sound quality/acoustics like intermittent voice, low volume, echo or other
noises, the possible reasons could be:

Users are seated too far out of recommended microphone range and sound faint, or are
seated too close to sensitive microphones and cause echo.

The intermittent voice is mainly caused by packet loss, due to network congestion, and
jitter, due to message recombination of transmission or receiving equipment (for example,
timeout handling, retransmission mechanism, buffer under run).

Noisy equipment, such as a computer or a fan, may cause voice interference. Turn off any
noisy equipment.

Line issues can also cause this problem; disconnect the old line and redial the call to ensure
another line may provide a better connection.
Wi-Fi and Bluetooth Issues
Why is the wireless signal strength low?
Ensure the IP phone and your gateway/ router are within the working range and there is no
obvious interference (walls, doors, and so on.) between them.
Why can’t I connect the Bluetooth device with the IP phone all
the time?
Try to delete the registration information of the Bluetooth device on both IP phone and
Bluetooth device, and then pair and connect it again. Contact Yealink field application engineer
and your Bluetooth device manufacturer for more information.
Why the Bluetooth headset affects IP phone’s voice quality
？
You may not experience the best voice quality if you use a Bluetooth headset while the 2.4 GHz
band is enabled or while you are in an environment with many other Bluetooth devices. This
possible loss in voice quality is due to inherent limitations with Bluetooth technology.
