Anyone using this?

It's basically voicemail for your PC.

I've been trying it out for the last couple days,free version and find it to be pretty darn good.Nice to be able to sit down at PC and playback messages. Might come in handy when I'm traveling overseas as well.

I believe it may send an sms message to cell callers, but that doesn't bother me.

From their ad-
"By helping your phone and PC buddy up (like iPod® and iTunes®), our services help you do amazing things. Like screen calls on your PC, get faxes by email, save voicemails for as long as you want and more. And usually for free (or pretty cheap)! See why the buddy system isn't just for kids."
