Hi Sunil,

I belive it is the only flow published for music on hold.  However, as
the document states, it is not the only way it can be done.  Previous
versions of the document have shown using a REFER to a Music On Hold
server, in which case B can crash.

In the current flow which uses B as a 3pcc, if B dies, A will just hear
music until either they give up or the Music Server times out and stops
streaming music.

Thanks,
