On our 3640, normal modem users dial up and login, using a radius server, with no problem. We decided to allow ISDN users to also dial into the 3640. So far, my ISDN line makes a connection but never prompts me for a username and password in the Terminal Window as a normal modem would. We've also thought about changing the authentication for ISDN from the radius server to the 3640 locally. Any help would be appreciated.
