We're trying to configure dialup over PSTN to ISDN BRI then onto a bank of MICA modems. Once this is all done, we'd like to authenticate using RADIUS and RSA/ACE server. We're using a 3640 Router (12.0(28d)) and a BRI S/T 4-port adaptor (not WIC) which should work (after not realising that ISDN WICs don't work). We've followed the online config. guides to enable us to get this going. We see the call hit the ISDN functionality, but do not see any modem activity or PPP activity.
Can anyone advise us further?
Here is the config: -
