Explanation

The root cause is bandwidth contention: the new cloud document application is consuming internet bandwidth and causing VoIP packets to be delayed or dropped. Configuring QoS (Quality of Service) rules at the internet router to prioritize VoIP traffic is the least expensive solution because it requires only a configuration change to existing hardware - no new equipment or ISP contracts. QoS marks and queues VoIP packets with higher priority so they are transmitted before bulk data traffic. Adding a second internet link (A) is expensive. Creating VLANs (C) separates traffic internally but does not address internet bandwidth contention. Using a higher-compression codec (D) degrades call quality and does not fix the root cause.
