Hi Partha,

Is an example of this the same music on hold audio stream existing as
the same MS within multiple CSs? If so, then I understand your
requirement to be that the SRC be able to indicate multiple instances of
this audio stream within several CSs as being the same MS. Is that
correct?

Thanks,
Charles
