Refer to the exhibit.
There is a call flow between Phone A and Phone B. Phone B (holder) places Phone A (holdee) on hold. Which MRGL and Audio Source are played to Phone A?
A. MRGL A and Audio Source 4
B. MRGL B and Audio Source 2
C. MRGL B and Audio Source 4
D. MRGL A and Audio Source 2
“In simplest terms, the holder’s (phone B) configuration determines which audio file to play, and the holdee’s (phone A) configuration determines which resource or server Will PLAY that file.”
So i agree the answer is D.

“…As illustrated by the example in Figure 18-1, if phones A and B are on a call and phone B (holder) places phone A (holdee) on hold, phone A will hear the MoH audio source configured for phone B (Audio-source2). However, phone A will receive this MoH audio stream from the MRGL (resource or server) configured for phone A (MRGL A).”
