I switched to linphone and twinkle (via diamondcard.us) as soon as Gates bought skype. Microsoft usually figures out some way to monetize whatever it acquires. Or kill it, if Microsoft has an alternative. Linphone works about the same as Skype, though it has a few rough edges. So does ekiga, though I don't use ekiga. Latest version of linphone and twinkle are in the repositories already. Ekiga is in too, but I don't know if its the latest version.
