Hi
I had the same problem, seems to be some sort of a bug in the program.
If you parse ivm.exe -outbound "number1;number2;number3"
The two first numbers is complete, but the last number is chopped. However, I found a work-around. If you add a blank space after the last number, it works.
Example:
ivm.exe -outbound "88888888 "
Stupid, but it does the trick.
Regards Henrik
