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.
