voip, wireguard

Hello, I’d like to have possibility to compile wireguard, currently it is not possible due to issue with linux headers.
Another thing that mumble is good, but it is suitable for gaming. I’d like to possibility to install real voip/SIP, like openSIS/Kamilio or freeswitch. I use rock64. Thanks.

PS did you consider to join with Arch arm? I think dietpi and arch philosophy are about same things, about lightweight, and freedome to choice.
