The correct answer is C. Set the Endpoint Multipoint mode to "MultiWay." E. Set the Endpoint ActiveControl mode to "Auto"..

Question
Users are reporting that when they receive a second video call on a Cisco TelePresence EX60 and press "Accept and Merge", they can hear the audio but cannot see the video. Which two actions should an engineer take to fix the cause of the problem? (Choose two.)
Options
- ASet the Cisco VCS Call Policy configuration to "Local CPL"
- BSet the Cisco VCS Conference Factory mode to "On."
- CSet the Endpoint Multipoint mode to "MultiWay."
- DSet the Endpoint DefaultCall protocol to "SIP."
- ESet the Endpoint ActiveControl mode to "Auto".

Why each option
The 'Accept and Merge' feature on a Cisco TelePresence EX60 requires both MultiWay multipoint mode and ActiveControl to be enabled so that merged calls carry full video, not just audio.
Setting VCS Call Policy to 'Local CPL' governs call routing and admission rules on the VCS and has no effect on whether the endpoint can display video in a merged multipoint call.
Conference Factory on Cisco VCS enables ad-hoc conference creation by dialing a factory URI, but enabling it alone does not resolve the endpoint's inability to show video during an endpoint-initiated merge.
Setting the Endpoint Multipoint mode to 'MultiWay' enables the endpoint to invoke a Cisco conference bridge (such as Cisco MCU or TelePresence Server) when merging calls. Without MultiWay, the endpoint falls back to basic audio-only mixing and cannot establish the video streams required for a multipoint video conference.
Setting the DefaultCall protocol to SIP controls the signaling protocol used for outbound calls and does not enable video in merged multipoint sessions.
Setting the Endpoint ActiveControl mode to 'Auto' enables the iX application layer protocol, which carries conference control signaling between the endpoint and the conferencing infrastructure. ActiveControl is required for the endpoint to negotiate, receive, and render video layout data when calls are merged using 'Accept and Merge'.
