Yes, it is. I've used it in Whonix, with OpenVPN to handle both TCP
and UDP. Basically, you setup an OpenVPN server (using PKI) in one
Whonix workstation VM, and configure a hidden service in the Whonix
gateway VM that points to it. Then you install Mumble in the workstation
VM, and setup a server pointing to localhost. To avoid IP conflict, you
must change the gateway-workstation network from default 192.168.0.0/24
to 192.168.1.0/24 (or whatever).
Others using Whonix install OpenVPN and Mumble. The OpenVPN clients
connect via SocksPort, using OpenVPN's "socks-proxy server port up"
(where up contains the username/password for the local Whonix gateway)
and "socks-proxy-retry" options. The Mumble clients connect (via VPN via
Tor) to the Mumble server at 192.168.1.11 (or whatever IP the remote
workstation VM is at).
There's considerable latency (1-2 seconds) but sound quality is
otherwise excellent, better than typical cellphone. Mumble is designed
for in-game conversation, and includes an excellent quality-optimization
But that's mostly of historical interest, I think. I see that Linphone
works well via OnionCat.[1,2]. And Linphone uses the standard SIP
protocol, so you're not limited to users on a particular Mumble server.
