[guardian-dev] onion address for SIP TCP (non-TLS) port

[Hans-Christoph Steiner]

Has anyone ever tried using an .onion address for the SIP TCP registration
port (5060)?  There would be no need for TLS, since the Tor Hidden Service
would provide the connection encryption.

This would help make SIP a lot more private since the SIP TCP/TLS is always
connected, and that connection can be used to track users, especially if it is
an organization's SIP server with a small user base.

I'm guessing this should be workable since the TCP port provides the signaling
and registration, and the RTP media streams are totally separate.
