Multiple Voice Chats

I find myself in need of a chat client of sorts. I use Yahoo and AIM and those work fine for me, but someone I chat with needs to be able to speak to multiple people at the same time without starting a conference.

Basically, just like yahoo but allows us to do multiple private voice chats at the same time.
Pidgin and Trillian didn't work out so well. It doesn't have to be able to chat with other clients. We're just looking for one good yahoo replacement that allows multiple separate voice chats.

*sigh*
All that does is give me "free voice chat programs". It doesn't show me which ones are safe, which ones are reliable, and it CERTAINLY doesn't tell me which ones allow people to chat to multiple random users privately at the same time. It's not a common feature, so I'm pretty sure whatever voice chat program I'm looking for will have such a unique ability listed as a feature, or even as part of the title.

Which is why I gave up and came here. I know you guys are sick of seeing me so it's not like I'll come here without trying to figure things out on my own first. But everybody here has their own wealth of computer knowledge and I figured someone would have had some experience with the type of chat program I'm looking for.

Ventrillo
Teamspeak

Those might just do it. Thanks for the tip.

I heard Ventrilo costs money to host your own server, and we can't exactly have other people listening in on us on a public server. ^^''

Would teamspeak cost anything to host our own server?

EDIT: (Sorry for the double post.) Teamspeak won't work because it requires us to submit personal information even for a free license, and the party interested does not wish to do that.
Ventrilo might not work if it costs anything to get a server, or requires personal information.

Oh look, right there 4th from the top. Maybe instead of glancing at the first couple of results you should actually click the links and read what they're capable of, then we wouldn't have to deal with your 153 threads a week about simple computer issues.

...without starting a conference.

Do you mean like...
talk to person A
<mute mic to A>
talk to person B
<mute mic to B, open to A>
talk to person A

that kind of thing?
In which case good luck because I dunno anything that does that.
