CompTIA Network+ (N10-007) — Question 639

Which of the following can be used to enable and translate the communication between legacy non-IP phone systems with solutions for voice communications that can run over the Internet?

Answer options

Correct answer: D

Explanation

The correct answer is D, the VoIP gateway, as it specifically enables the integration of legacy phone systems with VoIP technology, translating the communication formats. Options A, B, C, and E do not provide this specific functionality; a media converter is for different media types, RTP is a protocol for real-time data transmission, ISDN is a circuit-switched telephone network, and a SIP trunk is a virtual version of an analog phone line.
