seems to be supported

also an alternative to skype, preferrably foss would be nice
crossplatform would be even nicer (linux/windows/android)
tried linphone but its kinda rough
something sip-like stuff, independent protocol

any ideas?
this is the first major hardware inconvenience in 2 years since im all-linux :)
so anyway im happy
