[asterisk-users] Ringtone to a member queue

[Diego]

Hello everyone, I configured a queue with dynamic agents for a small 
proyect, normally only 1 member in the queue for ansering calls would be 
enough. But I need to configure a ringtone or any other signal to 
comunicate to the member's queue other call cames into the queue and the 
member could decide if park the first one o keep the second one in the 
queue. 
I appreciate any help from the group.
