Explanation
When addressing call quality issues between IP phones, the Real-time Transport Protocol (RTP) is the primary protocol to analyze. RTP is responsible for the actual transmission of voice data during a call, and its performance directly impacts call quality. Key factors affecting RTP and, consequently, call quality include: Packet Loss: Missing packets can lead to audio gaps. Jitter: Variations in packet arrival times can cause choppy audio. Latency: Delays in packet delivery can result in noticeable lag. Analyzing RTP streams allows technicians to identify these issues and implement appropriate Quality of Service (QoS) measures to mitigate them.
