H.323 is an umbrella Recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. Which CUBE configuration will support H.323 protocol interworking and address hiding?
A.
voice services voip
h323 interworking
media flow-around
B.
voice services h323 to h323
h323 interworking
media flow-through
C.
voice services voip
allow-connections h323 to h323
media flow-around
D.
voice service voip
allow-connections h323 to h323
Explanation:
Address hiding is a security feature of the CUBE which will hide the IP address of the originating gateway. This feature is turn on by default so we dont need to set it.A and B are not correct because the command h323 interworking doesnt exist (moreover A uses media flow-around feature which will turn off the address hiding feature).
C is not correct because it uses media flow-around feature too.
