Voice over Internet Protocol (VoIP) and cell phones offer unique advantages and disadvantages regarding call quality. Understanding these differences can help users choose the best option for their communication needs.

Quality Assessment: VoIP vs. Cell Phones

Factors Affecting Call Quality

• Network Reliability: VoIP relies on internet connection stability, while cell phones use cellular networks.
• Bandwidth: Higher bandwidth on VoIP can improve call quality, but low bandwidth can lead to issues.
• Latency: VoIP might face delays due to packet switching; cell phone calls usually experience lower latency.
• Packet Loss: VoIP calls are sensitive to packet loss, affecting audio clarity.
• Jitter: VoIP is susceptible to jitter, which can disrupt audio flow.
