8x8 tried the Granny Vid-Phone for a while. (Demo is here). At dinner at IT Expo, we were talking about Video Calling and Scott Wharton's name came up because he is rolling out video calling with VidTel.
A name that didn't come up was Nathan Stratton who is at BlinkMind. The BlinkMind service uses the Grandstream GXV3000 Video Phone, which VidTel also uses.
It will be interesting to see where this goes because of the upstream bandwidth necessary for video telephony to work well.
"Videl is initially providing a plug-and-play, out of the box videophone solution built around GrandStream's GXV3000 video phone - the phone supports SIP, H.264, bandwidth from 32 Kbps to 1 Mbps, has a 5.6 inch TFTP LCD screen and VGA camera. [FierceVoIP]
I have tried services like Oovoo and SightSpeed with some disappointment. They are actually half-duplex - only one side can talk at a time. The video is choppy even on my BrightHouse 7MBx1MB connection. Maybe I expect more at this point in time.
I would like to point out that many, many VoIP services that overlay on a Broadband connection have jitter, latency, low-quality service. And that's just audio, so I don't know what video will be like.
Also, since Oovoo is free and so is Skype - both of which do not require a $200 handset nor a separate monthly service - I have to wonder about the viability of the business model. Making it stupid easy for people to use and understand would certainly go along way in adoption though.
