Techniques to voice call passthrough between a Windows machine and Linux machine? (no skype)
 

Hello,

I would like a method to avoid using Skype but to simply use the terminal of my notebook (without X11).

My friend has Windows 7 and has also skype, but he could install a simply to use application that does sort of skype.
Since he has no ideas what is a firewall, the programm has to be like skype is: in other words, to passthrough, the firewalling over a third-machine, so does skype.

On Linux, all variants that are included into Debian are fine.

I hope you would have some ideas -- I am out of ideas, since it looks impossible.

What about a sort of SSH? He could get a programm that reverse it and open some port to allow voice call on his windows?

Thank you.

Straight chat messaging? Or are calls involved?

Are you using your terminal to communicate to this Windows user? Or vice versa?

If straight text: CenterIM is a text-mode multi-protocol instant messaging client for Linux, *BSD, Solaris and other Unices. The program supports most of widely used IM protocols, including AIM, ICQ, IRC, MSN, QQ, XMPP (Jabber), Yahoo.

Hindsight editing: I am not sure I helped at all here. Sorry about that.

Thank you about centerim. I know centerim. Centerim is cool for chat under console, but it has no voice phone calling.

The GOAL:
voice phone call over ip, such as voip

the Windows user can use graphics.
The linux user would like to use pure console.

The guy using Windows has no clue what is a router, and he will not do changes on it to enable a special port.
It would be nice that it works are simple as skype to allow to go through any NATs (most of them).

I am looking forward to hearing you.
