Ringtone to a busy member queue

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.

A simple solution would be to set your queue to ring members that are in-use with ‘ringinguse=yes’ in the configuration section for your queue in queues.conf
