Hi Vincent
The config on both routers look like this (except for the IP addresses being different, of course). I have removed some of the more sensitive information, but take my word for it that connectivity is not an issue. ;-)
We are using interface s0/1 on both routers for this 320K link. The PABX IP address on site A is 10.30.200.1, and on site B is is 10.34.200.1.
