I am trying to set up Ekiga to work as a Softphone for VOIPo in Ubuntu 9.04 (Jaunty), but I am not sure how to match up the settings. I have searched with Google, but have not found the answer.

In the VOIPo VPanel I under "Features > Preferences > Softphone / BYOD" it says:
Hostname: sip.voipwelcome.com
Username: my phone number
Password: my secret password

In Ekiga when I try to add an SIP account I see the following fields:
Name: __________
Registrar: __________
User: __________
Authentication User: __________
Password: __________
Timeout: __________ (prefilled to 3600 by default)

I am sure that I am overlooking something very simple, but I have not been able to figure out a configuration that Ekiga will accept. If anyone else is using Ekiga I would really appreciate any help that you could offer in how to configure the account there.

Thank you.
