I am not IT proffessional but I need to set up Cisco 801 ISDN router in order to accept an incoming ISDN connection call. Is it possible to accomplish that with 801 and if it is possible how do I do that?>
You can have dial ins allowed in your isdn router using either the configurations with the BRI interface or with the dialer interface which you can configure manually.
And again you can have authentication enabled either chap or pap between your sites.
Also take care of intersting traffic which has to trigger the dial out from the remote location.
Also refer these links which can be of some help to understand the configuration parts invovled in it.
