OpenSuse ISDN problem

[jcreppes]

I've got 2 ISDN cards in a server with Opensuse 11.2 as OS.
Both cards are (according to lspci) the: "Cologne Chip Designs GmbH ISDN network controller [HFC-PCI] (rev 02)"
These are configured with yast2 with the correct countrycode.

The Hisax driver (module) is loaded.
This way I should be able to call with the program "minicom", configured as ttyi0 with pre command: ATZ^M~AT&E0000000000^M~ATS18=1

The zeros after AT&E is the phone number of the line which the card is connected to.
If I then call a number with ATD or ATDT, it says "BUSY".

When I call to my ISDN card, minicom says "RING" and shows the number of the caller.
But when I try to answer with the "ATA" command, it says "NO ANSWER"

Dmesg shows "isdn: contr0,ch0 cause: E001B" after each time I try to call or answer.

With only one card plugged in I get the same results.

I tried other linux distro's but some couldn't be installed on the Proliant ML110. Also I've read that Suse has best support for ISDN.

Does anyone know what the problem could be?

Never used isdn on suse, but look at the linuxhow-to:
Linux Online - Modem-HOWTO: Troubleshooting

Looks like you have a problem with 2 serial ports.
To test, try using 2 boxes with a single modem in each and then see if the 2 modems talk to each other.
If yes, then you need to look at the serial port setup in the single pc.

Sorry can't give more help, but it's years since I last used dial-up!
