It would be useful to have a setting so that a different type of chime is played for the initiator of the emergency broadast.

When a user initiates an emergency broadcast, the calling badge plays the new_party.wav  sound file before the mic goes live. The same sound file is played when a typical call is connected.
 
Some users are confused when initiating an emergency broadcast since it plays the normal chime and so they are not sure if they are in a true panic broadcast or not.
