I just purchased a 871 router trying to connect a small office over a DSL internet connection using IPSec VPN tunnel to the Corporate office Cisco 3000 series VPN concentrator. The VPN tunnel will need to support both voice and data and possible video in the future. I am running CallManager at the Corporate office and there will be Cisco 796x phones at the remote office. I am not sure where to start as far as design and configure the tunnel.
Can someone share their success experience on this type of setup ?
Any documentation on this type of setup is greatly appreciated !!!
