Hi,
I' m trying to configure a Cisco 3640 with 4 BRI and 12 Digital Mica Modem.
Callback with analog modem is working fine.
I' m having troubles with ISDN callback.
On ISDN q.931 debug cisco router, when it starts to call, receive the following message:
02:01:27: ISDN BR2/3: RX <- DISCONNECT pd = 8 callref = 0x97
02:01:27: Cause i = 0x80D8 - Incompatible destination
I'm using ios vers. c3640-i-mz.122-13b.bin but I also tried other IOS versions.
As ISDN TA on client I used Digicom Palladio ISDN-USB and Zyxel
This is the cisco configuration:

During the call IN we see the following:
Calling Party Number '103071401', Plan:ISDN, Type:
Called Party Number '103072700', Plan:ISDN, Type:National
During CALLBACK, the number dialed is:
Called Party Number '0103071401', Plan:Unknown, Type:Unk
We see a Zero before the called number....not sure why. As a simple test try making an ISDN call from this 3640 & see if it connects with which number,
3640#isdn call interface bri2/3 0103071401
AND
3640#isdn call interface bri2/3 103071401
deb isdn q931 / deb ppp nego / deb dialer / deb callback will be helpful.
For ISDN q931 cause code:

We have tested dialer string and it worked fine. The phone number we used was 0103071401.
We have tried a wrong phone number and we receive an ISDN message that the phone is bad.
We have tried a lot of debug (but not deb callback) .
When the router callback the pc no ppp negotiation start because the call stops at ISDN level.
Thanks for help

You are using Basic-Net3 as your ISDN type, are you sure this is correct for your country? (don't know where you are located)
Something else I see that will resolve a lot of headaches later:
- Change your dialer callback to PERMIT otherwise you can have problems cancelling callback.
- Use rotary groups instead of Dialer Pools as the pools cause problems with multiple isdn users connecting. Remove the dialer pool statements and add into the BRI's dialer rotary-group 1 This points to the dialer 1 interface, where you will have to add the dialer in-band statement.

The router is in Italy and we use Basic-Net3.
I already tried dialer callback to PERMIT and dialer rotary-group insted of dialer pool with no solution
I don't remember if I used both together, I' ll verify it again at the end of the week.
Thanks for the info
