hearning annonce when user is active

[eslim]

I have Avaya CM6.0

I have users with multiple call appearance

I want to hear announcement when the station is active ( in call). when the user become available, the call will be routed to the caller.

example: 1001 call 1002
when 1002 is active, 1001 will hear announcement ( music)
when 1002 become availbale, it will receive the call

the caller 1001 still in queue hearing the announcement until 1002 becomes available.

Please how we can do it?

Thank you for your answers
