When are you starting the VPN on your Asterisk server, before or after Asterisk has started? If after, and you are binding to 0.0.0.0, it is likely Asterisk is not actually bound to your tun0 interface. So, for a test, explicitly have asterisk listen only on the tun0 interface, retry your call.
Or setup your tunnel, then stop Asterisk and start it again, that should cause it to bind properly. -- Paul Belanger | PolyBeacon, Inc.
