Jitter
Suggested answer: D

Explanation:

Jitter is most likely causing the issue of intermittent one-way audio and dropped conversations for the company that uses VoIP telephones. Jitter is a variation in delay of packets arriving at the destination. It can cause choppy or distorted audio quality for VoIP applications, especially over WAN links that have limited bandwidth and high latency. The recommended jitter for VoIP is less than 10ms1. The company has recorded ping times that exceed 50ms, which indicates high jitter and latency on their network. Reference: https://www.voip-info.org/voip-jitter/ 1
