Voicemail live

I’m new to freepbx and I just set up a system with a Pika warp appliance.
I’m quite satisfied and everything is working.

Now the customer is asking me a simple feature and I’m not able to create it.
He wants to able to listen to voicemail as they are left, just like any cheap answering machine.
I tried to find a way to send the caller in voicemail AND to an extension at the same time, but without any luck (I have yealink phones with autoanswering and mute intercom).
Then I tried to find a way to play the message left in voicemail just after it is finished, but I can’t automatically generate the call (I’m able to do it pressing the button in recordings page, setting CallMe number as *80XXX for intercom).

Help me please, I’m stuck!
