Turns out that VoIP Buster program was the same as all the others. No luck. I woke up late today, my mom left before I could get a ride to school. When I did wake, I tried calling from the comp, no luck.
In other news, I managed to get in touch with Grandma, got a ride to school, did a little volunteering and scored myself a 24-pin power supply for the summer. Hooked it up to the nice board, powered on, got some beeps, and it self-terminated. Didn't expect much more from Power Supply+Motherboard. Still looking for a Linux OS for it to run.
