Sample answer
“VoIP, or Voice over Internet Protocol, allows voice communication to be transmitted over the internet instead of traditional phone lines. Its advantages include reduced costs for long-distance calls, the ability to integrate with other internet services, and scalability for businesses. For example, a company can easily add new lines without significant infrastructure changes. However, it's essential to consider potential issues like latency and network stability, which can be managed through proper quality of service (QoS) configurations.”
