Aside from a computer and Internet connection, what is essential for Voice over Internet Protocol communication?

For Voice over Internet Protocol (VoIP) communication, a microphone is essential because it captures your voice, allowing you to transmit audio during a call. While other devices like webcams, headphones, and external speakers can enhance the VoIP experience by enabling video communication or improving audio quality, they are not strictly necessary for the basic function of making a voice call. The microphone is crucial as it provides the means to speak and send your voice to the other party, making it the fundamental device required for any VoIP interaction.
