A company would like to provide customized voice prompts for users who are dialing into videoconferences. Which component should be used to support customized voice prompts?

A.
Cisco CallManager

B.
the IVR built into the gateway

C.
the IVR built into the video gateway

D.
Cisco peripheral gateway

E.
the built-in IVR of the MCU

Explanation:

A 3500 MCU is acting as gateway (IPVC 3521, 3526 or 3540 with gateway module called MCU gateway) than answer E is correct, but answer C seems to me also a correct answer as we are talking here about a video gateway device with built in IVR.
