Re: [tor-talk] VOIP over Tor

[Maimun Rizal <maimun.rizal@xxxxxxxxxxxxxx>]

Hi,
I have researched VoIP over TOR, I use openVPN to communicate voip client with tor network. 
I test with default tor - 3 nodes and modify tor with 2 nodes. 
With 3 TOR nodes, from 100 call, only 21 call which have acceptable quality call, whereas with 2 tor nodes, i got 36 acceptable quality call.

We should concern with recomendation for real time voice communication. ITU G 114 recomendation, maximum latency should be less than 400 ms. Others recommendation are jitter (less than 30 ms) and packet loss ( less than 5 %).

I did test only for nodes in european.

Regards,
MR
