Hi, 
In fact, I mean that once there is an incoming call, phone server will
broadcast this event and any application can register it.e.g., diaer
application, music player application, etc. 
When music application receives this event it can then pause itself.
Unfortunately, in the current code, phone server sends incoming call
event directly to dialer app and music app has no chance to receive this
event. Therefore, in the following version, I suggest we should revise
phone server's ability.
