compare to skype ,
which is better ?

It depends on how do you perceive really.

If you wanna compare the user base, it's no where near to skype.

But one thing worth mentioning is that it has integrated call recording and voicemail feature is free too

so ...one word, the word " complicated " for gizmo for new users
call recording ?
can record the whole call process ?
