Our application is to have both data and voice communication from one console based system and isdn network.
I have ISDN card for voice, RS422 card for data and one relay card for some relay switching functions.
I am getting unexpected_kernel_mode_trap(double_fault) error in our ISDN card driver when i am getting incoming voice call on the PC.A blue screen appears and the system reboots.This problem occurs may be after 30 incoming calls.This number is not fixed . It is so happened that the dumping problems comes may be after 100 or 500 or even sometimes 1000 incoming calls.
what may be the problem? Can any ne help me out in resolving.
Any patch sort of thing is there to handle such exceptions.
My PC configuration is
windows 2000 SP4
