The VB application will work as call manger. The (GSM modem) receive a call and forwarded it to a specific number in each day (the number can be change) and let say for on monthly, i only upload such a file (txt,xls) to VB software and he will do the reset by controlling the GSM modem. the computer will stay switch ON for month to contolling the GSM Modem.
in each day the application should automatically forward for a call to a new user.

Day 1 0097777777
day 2 0988788777
day 3 0544852222

It is pretty easy if we use Telephony API (TAPI) library for handling the call: receiving, forwarding, hanging-up, etc. Although I could send you a demo for this purpose. Contact me for demo request
