Ive got an existing setup with a remote and local router.
The local router runs ccm and uplinks to pstn via fxo ports.
The remote router has some voip phones that get ip addresses from a local pool.
I have an ipsec tunnel setup between the 2 routers. An acl directs traffic between the remote site's local ip pool and the local site's loopback address across the tunnel.
I have now installed an fxs module on the remote router and am trying to figure out how to direct its traffic across the tunnel.
