What term describes voice features within IP technology such as voice calls and voicemail?

Explanation:
Voice over IP, or VoIP, is the term for delivering voice services over IP networks. It enables voice calls and voicemail by converting audio into data packets that travel over the same network used for data, integrating voice into the IP-based system. The other options don’t describe the overall voice feature set: PSTN refers to the traditional telephone network that uses circuit switching; VPN is about creating secure connections over a network and isn’t specific to voice features; SIP is a signaling protocol used to set up, manage, and terminate VoIP sessions, not the general label for IP-based voice services. So VoIP best captures voice features within IP technology.
