Some days ago i installed ekiga and now i start it all days :)
This is a lil howto use Ekiga to talk with people using other networks like Gizmo and VoIpBuster and of course the ekiga network .

First of course you need to isntall Ekiga :

# emerge ekiga

And install the driver for your cam, my cam is a logitech so first you need a kernel with v4l (video for linux) enable and:

# emerge media-video/usb-pwc-re

Now when you plug your webcam you will see how the cam is assigend to /dev/video0. In ekiga you need to select the V4L or V4L2 driver to use it. It will work w/o problems in amsn too.

So how to talk with other networs? is easy just add new accounts:

* Gizmo:
Acc. Name: Gizmo
Register: proxy01.sipphone.com:5060

Pass: yourpass

Auth. User: 123456789 (your SIP number again)
Reign/Domain: proxy01.sipphone.com

Now to call any Gizmo user just use:
