Get poor sound quality during a callGet 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.
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, bufferunderrun).
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.
There is no sound when the other party picks up the callThere is no sound when the other party picks up the call
If the caller and receiver cannot hear anything - there is no sound at all when the other party picks up the call, the possible reason could be: the phone cannot send the real-time transport
protocol (RTP) streams, in which audio data is transmitted, to the connected call.
Try to disable the 180 ring workaround feature.
