I have several Atom based boxes running OpenVPN and processing up to six
simultaneous calls over it with no issues. I am quite sure it could do
more. Load is still at .2 :)

I use openvpn for VOIP traffic all the time. It's not a commercial
application, and only one simultaneous call usually on each vpn link,
but I even have a VPN client on a Linksys WRT-54g wireless router with
1 phone behind it - it works flawlessly, so it does not take a lot of
CPU to run a vpn connection.

Hi List,
Our company has several small distributed offices we would like to
inter-connect with bridged VPN a single subnet (last example in
http://www.shorewall.net/OPENVPN.html). We have SIP phones in every
office (up to 5) so we can use SIP without any NATing and securely.
Max theoretical simultaneous calls possible ~30, but we have ~5-10 @
regular basis.
OpenVPN server would be in the same datacenter like Asterisk PBX (in
one physical subnet). Asterisk and OpenVPN are virtualized XEN guests.
I wonder about overheads, system loads and other possible gotchas in
this setup. Is there anything I should (re-)consider before
implementing this? Anyone had difficulties running VoIP or VPN traffic
over (virtualized if it makes any difference) VPN?
We use mainly g729 and speex, and very little g711.
Regards
Motiejus
