Call-In shows?

[CreamCow]

I realise there have been plenty of posts about this, but I think I may know a little about this already. I used to call into a show a few years back using some telephone program on the computer. It was a constant feed back and forth, very nice. I forget what it was called, but I do know it worked with ICQ well. Anyway, the guy I asked who used to do the call-in show said if I wanted call ins, I'd need 2 sound cards. Currently, I have 2 computers, one has a soundblaster Live X-Gamer and on board sound from the mobo. The second computer uses a SoundBlaster Live Value card. I have the ability to run both computers at the same time and on the internet at the same time. I also have two microphones. Is there any way I can get a simple and free telephone program for my listeners to download and call me on? And how would I set the computer(s) up to have a call in show? I'm also running Windows XP pro if that helps.

Check out this thread. I think there's another way of doing it, but here's my contribution for right now.. Sorry if this didn't help, but someone will come along.
