Hi,
One possibility that you might want to explore is OpenVPN. If your VoIP
clients support OpenVPN (either through a local Openvpn client on the
clients network being used as an OpenVPN gateway, or through individual
clients supporting OpenVPN (laptops with softphones, or I've heard of
one particular hardphone supporting OpenVPN - but can't remember which).
Once you are using OpenVPN - it is a bit easier to setup a failover
scenario - or even load-balancing - as Openvpn has some inbuit
functionality in this direction. There has been some recent discussion
on the OpenVPN list about load balancing and failover setups if I
remember correctly.
Just a thought,
Sebastian
