Re: [tor-talk] Tor VoIP PBX Architecture Discussion

Hello All,

We had a discussion on IRC regarding this and the following suggestions were made:

1)	Change the architecture to FreeBSD box<—> Tor <—> OnionCat <—> Asterisk, or even drop the FreeBSD box completely if the Asterisk box is able to handle the load.

2)	Traumschule is looking into creating a wiki page or opening a ticket for this project.

3)	Every alternate solution we looked at didn’t have the advantages that this solution had, which is the ability to provide PSTN access and interconnections to public Internet XMPP servers.

4)	Results of a test were conducted and one second round trip latency was noticed from PSTN to a soft phone connected via Tor (via OpenVPN). Hopefully performance improvement will be noticed with OnionCat.

If there’s any questions, comments, or suggestions, or if there’s anyone that’s willing to volunteer their time in helping out with this project please let us know. It would be greatly appreciated.

SSHD and OpenVPN are exposed as hidden services via Tor. The Tor user connects to Asterisk via a passwordless OpenVPN or SSH tunnel to route UDP traffic to Asterisk.
