Ekiga is the default SIP and H.323 compatible VoIP, IP Telephony, and Video Conferencing SoftPhone application for Ubuntu. It allows you to make audio and video calls to remote users with SIP or H.323 hardware and software over the internet. It is compatible with Windows Messenger and most VoIP applications, however it is not compatible with Skype or Google Talk. If you have the right SIP provider you can call out to any normal phone line.
Ekiga features STUN support, so it works seamlessly through your router and firewalls.

Ekiga is capable of running simultaneously with other sound appilcations. For configuration advice, see [http://wiki.ekiga.org/index.php/Getting_several_applications_using_the_sound_card_at_the_same_time_%3F Ekiga's wiki]. Setting output and input devices in preferences to default should be enough if you are using Dapper.
Snapshots
You can get the latest snapshots from here: [http://snapshots.voxgratia.org/] Installing them solved my problems with PC-to-phone calls. But be aware - they might be buggy and stuff. A good thing to do before installing those is to uninstall all pwlib opal or ekiga packages you already have installed.
