A ring tone service is provided to a called party upon receiving a call
from a calling party at a device of the called party, where the device
annunciates the call according to a particular ring tone as determined by
the called party. A network-based call control manager receives a
notification that the calling party is calling the called party, and the
call control manager queries a network-based ring tone manager to
determine the particular ring tone. The ring tone manager notifies the
call control manager of the determined ring tone, and the call control
manager sets up the call to be annunciated at the device of the called
party according to the determined ring tone.
