I have a 3640 router acting as a remote dialin server for PC clients over two ISDN30 lines. My config is below, I am unable to dial into this router. Can anybody see a problem?
Thanks for your time !

If these are modem users, then try adding the following:
interface Serial0/0:15
isdn incoming-voice modem
!
line 33 94
modem dialin
autoselect during-login
autoselect ppp
It looks like you can remove the config for Dialer0, it's not being used.
To troubleshoot, try each of these steps in order
- debug isdn q931 - make sure the calls arrive and are answered
- debug modem - make sure the modems train up and answer
- debug ppp neg - make sure that PPP negotiates and an address is assigned

No joy,
Do the serial interfaces look correctly configured to you?

You've never specified if these are async or ISDN users dialing in. If they are async, the only command you need under the serial interfaces is "isdn incoming-voice modem". For sync ISDN users, the configs look fine except that Serial0/0:15 should have PPP authentication enabled.
Again, if you are having problems still you should enable the debugs to see what is going on.

Hi,
In the D-channel configuration of your PRI port (Ser0/0:15 and ser0/1:15)
IP processing should not be used.
As Joy said, the modem/line configuration need to be done to allow dialin access.(If you have installed the MICA bank in slot 1 .. line 32-64, slot 1 65-96)
line 32 62
modem DialIn
the following config should work fine for dial in access of Async/ ISDN
interface serial0/0:15
no ip address
encapsulation ppp
dialer-group 1
isdn incoming-voice modem
interface serial0/1:15
no ip address
encapsulation ppp
dialer-group 1
isdn incoming-voice modem
interface Group-Async0
ppp authentication chap pap dialin
group-range 33 62
interface Group-Async1
ppp authentication chap pap dialin
group-range 65 94
line 33 62
autoselect ppp
autoselect during-login
login authentication dialin
modem DialIn
line 65 94
autoselect ppp
autoselect during-login
login authentication dialin
modem DialIn
thanks
