Unidirectional Isdn connectivity
Hi,
I configured a pair of Cisco 800 routers to connect 2 networks bia an Isdn Bri link. Below a summary of the configurations and everything is working like a charm. I need now to change the configuration a little bit so that the call is allowed only when the router A calls the router B but not viceversa. How can I configure the router A to disallow calls from B?
Thank you in advance! Diego.
