A user is experiencing high latency when connected to the company's VoIP system. The issue persists even when the network is not being heavily used by other applications or services. What is the BEST initial step to troubleshoot this network issue?
Increase the bandwidth of the user's internet connection.
Ensure the latest version of antivirus software is installed on the user's device.
Completely redesign the network infrastructure to minimize bottlenecks.
Check and configure Quality of Service (QoS) settings on switches and routers.
To effectively address high latency issues, especially in VoIP systems, it is essential to check for quality of service (QoS) configurations as they are designed to prioritize traffic and could alleviate issues with latency by ensuring that VoIP traffic is handled first. Adjusting QoS settings can often resolve latency problems especially for real-time communications like VoIP, where prioritization over other types of network traffic is important. Other options, like designing the whole network or updating antivirus software, could be beneficial for general network performance but are less likely to have a direct impact on high latency specific to VoIP systems.
