We've done this with OpenVPN and it works fine. I'd recommend that the VPN server is not on the same box as Asterisk. Stick it on a firewall/gateway box giving access to the network containing the Asterisk boxes behind it. This way the Asterisk box(es) is seeing normal unencrypted traffic and the VPN server(s) can be specified to meet the VPN requirement.

Is anybody making calls over VPN? If so what is the "penalty" as<br>encryption is involved.<br>I was planning to use VPN to register Sipura units to my local asterisk<br>this way I don't have to deal with NAT issues.
