[cisco-voip] Securing Voice over WAN

[Scott Voll]

Topic came up at CIPTUG this year on securing voice and the overall idea is
to use VRF to get all your voice on to one VRF then firewall behind FWSM /
ASA / etc.

How do you work VRF if you have a WAN (T1 in this case)?  Can you VRF a WAN
connection?  VPN the traffic in?  Route-map it into the VRF instance?  Can
someone shed some light for me?

Thanks

Scott
