I know this is basic, but I'm drawing a blank, please help me out. When I call a cell phone from VOIP and hold the cell near the comp there's some sort of feedback noise that occurs in a frequent rhythm (the noise comes and goes every second or so). Is this an example of some kind of recursive process / feedback loop? By the way, I was using Skype for this experiment but I kind of hate Skype. I once had a VPS with Cent OS + PBX as an option for the OS and that made me wonder if I can just run my own VOIP service somehow so that I can make calls and maybe even have an associated phone number without having to suck off patronize big brother and get spied on just to have phone service?
