Possible to send all audio to multicast

Hello,
I am quite new to Volumio, thanks for this wonderful piece of software.

What I would like to ask:
I have some SNOM Phones and PA1’s (Public Announcement Systems). These devices are able to receive and play multicast (Multicast Audio ). So I can configure up to ten multicast addresses like 239.255.255.250 there to make them receive multicast streams.

Is there any way I can make Volumio send its output to multicast so that I can play it on these devices?

Thank you!
