Why each option
The Cisco TelePresence Codec C40 and the Cisco 7975 IP phone are the two devices among the listed options that support simultaneous voice and video.
The Cisco TelePresence Codec C40 is a purpose-built HD video conferencing codec designed to deliver simultaneous voice and video, making it a primary example of a combined voice-and-video endpoint.
The Cisco 7975G IP phone is a color-display IP phone that supports Cisco Unified Video Advantage, allowing it to handle simultaneous voice and video when paired with an appropriate camera.
The Cisco 7960 IP phone is a legacy model with no video capability - it supports audio calls only.
An intercluster trunk is a logical signaling path between CUCM clusters, not a physical endpoint device, and therefore has no voice or video capability of its own.
The Cisco 7940 IP phone is a legacy two-line audio-only device with no support for video functionality.
