I have a DMV1200 PCIe that was connected to a Panasonic PBX to PRI card and was working great.
Now I connect DMV1200 to a watson E1 modem.
protocol is NET5 , I disabled CRC , changed user to network but none of them worked.
how can I realize what is the problem .
I guess the question here would be what ISDN PRI protocol variant is configured on the Watson side in this case?
Such that you can match the same (if available for the DMV board).
