Agent announcement not working

I am using asterisk 11.we are in need of announcement for agent as when a call enters to a queue (finance).Before start talking with customer the agent should get the announcement of which queue this call is from. In gui there is an option called agent announcement …but here I made finance Queue in custom. I tried with
announce=/var/lib/asterisk/sounds/en/finance.wav in the queue settings. but its not working.
