Hello list, I am trying to connect an old ISDN PBX to my asterisk system. The setup includes an asterisk (1.0.9) running on the Soekris hardware, with an ISDN card (Billion BIPAC PCI), and I run zaphfc-bristuff-0.2.0-RC8k kernel module in NT mode (modes=1).
When I connect an ISDN phone to the card (using cross ISDN cable + 40v power supply), I manage to make calls from and to the asterisk. When I try to connect the ISDN PBX instead, still using the same cross ISDN cable and the power supply, I get rings to the right extensions of the ISDN PBX, but no call setup happens, and after 2 rings comes silence. I have tried this with NT and TE modes of the zaphfc kernel module (I thought it has to do with point-to-point or point-to-multipoint issue). I have tried it both with cross ISDN cable and normal ISDN cable (I just used Ethernet cable), all without any success (not even the mentioned rings). When this ISDN PBX is connected to normal ISDN line, it just works. If there is anyone with some knowledge about ISDN equipment and its integration with asterisk – I will be happy to get some advice – what to check or how is it actually supposed to work.
