Explanation
VoIP (Voice over Internet Protocol) relies on two key protocols: SIP (Session Initiation Protocol) for establishing, managing, and terminating calls, and RTP (Real-time Transport Protocol) for transmitting the actual audio data in real time. A bridge operates at Layer 2 to connect network segments and uses no voice protocols. A NAS (Network Attached Storage) provides file-level storage over a network and uses protocols like SMB or NFS. A modem modulates and demodulates signals for transmission over telephone or cable lines and does not use SIP or RTP.
