When using the IP phones, users complain that sound quality is poor and sometimes the voice heard is broken. Which section of the router configuration should the network administrator check in order to find the possible cause?
- access control lists
- interface bandwidth
- traffic queuing parameters
- routing protocol update settings
Explanation: If priority queuing is not configured properly in the router configuration, it will cause voice packets to drop because of congestion in the queues. The result will be delay and jitter. The voice traffic needs to be prioritized above application and data traffic.
