[asterisk-users] VoIP over virtualized VPN

[Andrew Hakman]

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.

> over (virtualized if it makes any difference) VPN?
> We use mainly g729 and speex, and very little g711.
