When an Emergency Alternate Greeting (EAG) is activated, which two of the following statements describe how the EAG is accessed?

A.	If it is active, the EAG is played before the welcome greeting of the system auto- attendant and the AtlGreeting.wav file is appended to the beginning of the welcome greeting.
B.	If it is active, the EAG is played before the welcome greeting of the system auto- attendant and a Boolean variable of "greetingactive" is returned as "true."
C.	If the EAG was recorded through the TUI and the EAG is active, the EAG overwrites the existing welcome greeting and the EAG is played until it is deactivated.
D.	If the EAG is included in custom auto-attendant scripts, a call to a subflow to checkaltgreet.aef must be inserted in the script at the desired location. If the EAG was recorded through the GUI, the new file replaces the existing welcome greeting and changes its name to WelcomeGreeting.old until the administrator deactivates the EAG and renames the existing welcome greeting.
