User Guide for Yealink VC110 Video Conferencing Endpoint

Why can‟t I hear the other site clearly during a call?

Ensure that the speaker volume of the far site is not set too low.

Muffled audio reception from the far side may be caused by highly reverberant
rooms. Speak in close proximity to the phone.

Adjust the priority order for your audio codec if you have chosen a low-bandwidth
audio codec to be first.

For best results, ensure that the caller is using a Yealink video conferencing
endpoint. Audio quality from your VC110 video conferencing endpoint will vary
when calling a non-Yealink endpoint.

Dust and debris may cause audio quality. Do not use any kind of liquid or aerosol
cleaner on the phone. A soft, slightly damp cloth should be sufficient to clean the
top surface of the phone if necessary.
Why is the voice quality poor?
Users may receive poor voice quality during a call, such as intermittent voice, low
volume, echo or other noise. It is difficulty to diagnosis the root causes of the voice
anomalies. The possible reasons are:

Users sit too far from or near to the microphone.

The audio pickup device is moved frequently.

Intermittent voice is probably caused by voice packet loss or jitter. Voice packet
loss may occur due to network congestion. Jitter may occur due to information
reorganization of the transmission or receiving equipment, such as, delay
processing, retransmission mechanism or buffer overflow.

Noise devices, such as computers or fans, may make it difficult to hear each other's
voices clearly.

Wires may also cause this problem. Replace the old with the new cables, and then
reconnect to check whether the new cables provide better connectivity.
