Cain's sniffer can decode which VOIP-related protocols?

Explanation:
VoIP relies on signaling to establish and control calls, plus a transport protocol to carry the actual voice data. SIP handles the signaling and session control, while RTP carries the real-time voice payload. Cain's sniffer includes analyzers for these two protocols, so it can decode SIP messages and inspect RTP streams to observe the voice traffic. The other choices are not VoIP protocols—they pertain to file transfer, mail, web traffic, or network services—so they’re not decoded for VoIP activity.
