Anyone know if there are any VOIP handsets available for sale? My parents live abroad and are about to get broadband, so I'm going to set up VOIP for us (and my brother as well) to save on long distance charges (I'll probably use a free program like Skype initially). However, I'd prefer to give my folks a handset to use rather than headphones. Anyone know if there are any PC telephony handsets out there (USB or better yet bluetooth or Wi-Fi)? I've tried googling but the results weren't great.
