Hi, I'm still trying to set up a dialing server. I've installed two ISDN cards, so I've configured four ippp devices. Then I've tried to connect to Internet, just to test, and it works (just testing on one b-channel, I don't care the others now). When I get incoming calls from an Office Connect ISDN Lan modem it doesn't works. On the Linux machine I've created a system's user, and then I've configured the Office Connect via the configuration wizard. I've tried to configure it with just specifying user, passwd and phone number but it can't connect (after that I've tried to specify an IP address on the Office Connect but I've had exactly the same problems). I have the following on the /var/log/messages: Jun 29 18:44:17 ras kernel: ippp0: call from 971XXXXXX -> 971YYYYYY accepted Jun 29 18:44:17 ras isdnlog: Jun 29 18:44:17 * Call to tei 127 from +34 971/XXXXXX, Mallorca on +34 971/YYYYYY, Mallorca RING (Data) Jun 29 18:44:17 ras isdnlog: Jun 29 18:44:17 Call to tei 67 from +34 971/XXXXXX, Mallorca on +34 971/YYYYYY, Mallorca CONNECT (Data) Jun 29 18:44:17 ras ipppd[95]: Local number: 971YYYYYY, Remote number: , Type: incoming Jun 29 18:44:17 ras ipppd[95]: PHASE_WAIT -> PHASE_ESTABLISHED, ifunit: 0, linkunit: 0, fd: 7 Jun 29 18:44:17 ras kernel: isdn_net: ippp0 connected Jun 29 18:44:17 ras kernel: isdn_net: chargetime of ippp0 now 126839 Jun 29 18:44:17 ras ipppd[95]: MPPP negotiation, He: No We: No Jun 29 18:44:47 ras ipppd[95]: IPCP: timeout sending Config-Requests Jun 29 18:45:17 ras isdnlog: Jun 29 18:45:17 Call to tei 67 from +34 971/XXXXXX, Mallorca on +34 971/YYYYYY, Mallorca Normal call clearing (User) Jun 29 18:45:17 ras kernel: ippp0: remote hangup Jun 29 18:45:17 ras kernel: ippp0: Chargesum is 0 Jun 29 18:45:17 ras ipppd[95]: Modem hangup Jun 29 18:45:17 ras ipppd[95]: Connection terminated.

In that case, Is necesary to use radius to make it work? Is there a simple way to make it work? Thanks in advance, Manuel Martínez Valls
