I wonder if there are plans to offer a "headless" mode where call-status is streamed to an FD instead of using a TUI. I'd love to be able to compose/wrap this tool outside of a terminal emulator.
I've been idly hacking on something quite similar but using QUIC instead. One of the downsides with QUIC of course is that it assumes TLS by default which makes it inefficient for use on encrypted transports (like wireguard, zerotier, tailscale, or yggdrassil.) I'll definitely give this a go as I'm a big fan of NNCP, another project by the author.
