Hello Woody,

I know that some people would argue with me, but you ought to go read the background of CU-SeeMe from Cornell University.

I have been using this product since the early '90s on the Internet, and it's one of the long-term players with both voice and video capabilities.

Obviously there is all the mainstream work with the H.323 standards, etc. and many new sources ... but they have been around for a long time (in Internet years) ... ;-)

Woody, prior to voice over IP there were some experiments done using X.25 packet switching protocols to transport facsimile, and even attempts at voice, back in the Seventies and early Eighties.

These were mostly folks who were working for "the company" at the time, and working in far away places (read: they wore trench coats on dress down day).

The fax trials were marginally acceptable, but voice didn't cut it over packet at all in those days when using x.25. Not until earlier this decade, except for Stratacom's adaptation of packetized voice.

In 1987 Stratacom did something slightly different. They used a highly controlled "box-to-box environment" back then to send voice, video and data over variable length packets in a T1 steam. Actually, this was a T1 mux using packet technologies, instead of straight TDM.

I would take Scott's lead, and try CUSEEME first, then go to NetSpeak, and VocalTec, and try Jeff Pulver's site at www.pulver.com. I seem to recall a time line, now that you mention it, on one of the sites. If I come across it, I'll post. You might want to try PMing Jeff here in SI. If he knows of a relevant source, I'm quite sure he'd point to it.

And you may also want to consider scanning the Frame Relay manufacturers, too. They were slightly ahead of themselves for a while, forcing voice over frame before prioritization schemes were in place, back in the early to mid Nineties, as well.

After '96-'97, the field started to pick up considerably, and "most" of those players are still around. I suggest you go after them on the phone, if you can't get what you need off their web sites.
