SIP services and softphones: what do you guys use?

[Dotan Cohen <dotancohen@gmail.com>]

I'm trying to get rid of proprietary Skype and two of my most
important contacts are willing to give SIP a try. We all installed
Ekiga and signed up for ~@ekiga.net SIP addresses, but the sound
quality was very choppy and unusable. They are both on Windows.

Is there an better softphone? Is there a better sip address service
than ekiga.net? Is there a better softphone for Windows than Ekiga?

Thanks!
