I'm currently struggling which SIP client software to use with respect to Ubuntu / Gnome. Some clients I've looked so far:
- Blink, seems promising but the Linux variant lacks a lot of features
- Twinkle Latest release is ~2 years old. AFAIK the only one capable of encrypting calls using zrtp.
- Empathy: default tool for IM on ubuntu
Some features I'd like to see:
- availablity of buddies
- conference calls
- call log
- desktop sharing (Blink seems to do that for Mac)
So my question is: what client software do you prefer and for what reason?
