Cross-Platform VoIP Software?

feilkin writes "With the release of Skype's Linux client, I'm wondering about alternatives. Namely, cross-platform solutions for voice communication. I've got friends who are using Windows, Linux and OSX, and I'm hoping that there is a way to communicate with all of them. I myself am using Linux, and I haven't been able to find any solutions that seem fitting to my situation completely. Does anyone have a solution that'll be useful on all three platforms, or solutions that may be coming in the near future?"

TeamSpeak

Sure, you can't talk to people who only have POTS.

Sure, its designed to be used with online games.

But really, its just IRC with voice. I talk to people in Australia with it all the time, for free. You can turn the bitrate down and even talk to people with dial-up. I usually just use gaim to tell someone "hey, join the teamspeak server, let's talk".

Also, this way I don't have to remember phone numbers.
