I use OpenVPN to pass both IAX2 trunking and SIP for a softphone on a 
laptop.  Works very well.

If the OpenVPN server is on a uClinux appliance, my first question is 
does the * server know how to route to the OpenVPN client address?  If 
the appliance is not the default gateway for the server,  a route to the 
OpenVPN client via the uClinux appliance address needs to be added.

Since the client is Windows, you do have to start the client (GUI) as 
'Administrator' otherwise the routing table does not get updated and the 
client cannot route to the server network.
