LOL. No I'm not trying to ruin my phone system... although my idea just might do that. I just want to take a few audio outputs from my computers and mix them in with my wireless phone headset that is connected to my phone line. I guess this idea is not possible? It seems like I should be able to do this, as I am not adding a signal to the phone line but a merged signal to the headset only. There has got to be a way to do this.
