People try to port Asterisk to non-Intel and non-Linux system, but zaptel is related to Linux and mostly to Intel
hardware.

Also, ztdummy isn't works well under VMware (which is very helpful for testing/debugging under high system loads),
because VMware's USB interrupts comes about 1 time of 6, so interrupt frequency is about 166 ints/sec instead of 1000
ints/sec required by zaptel.


WBR,
Paul.
