When experiencing voice break or poor call quality on VOIP calls, the following steps can be taken to identify potential issues in the LAN:
Check network bandwidth: The network bandwidth should be sufficient to support the number of VOIP calls being made. If the bandwidth is limited, it can lead to packet loss and voice break.
Check network latency: High network latency can cause delays in the transmission of voice packets, leading to voice break.
Check network jitter: Network jitter can cause the arrival of voice packets to be uneven, leading to voice break.
Check network congestion: Network congestion can cause delays and packet loss, leading to voice break.
Check QoS settings: Quality of Service (QoS) settings should be properly configured to prioritize VOIP traffic over other network traffic.
Check LAN cabling and equipment: Faulty or damaged LAN cabling or equipment can cause issues with network connectivity and lead to voice breaks.
By performing these checks, it is possible to identify the root cause of the voice break and take appropriate measures to fix the issue.
