Well the intercom has been installed and operational for over 8 months now and I am fairly confident in its design. My employer would like me to build a second intercom identical to this one but with two-way video. I've done a lot of reasearch and one way video seems to be fairly common but two way is not to be found, even in commercial products. I did find two products that supposedly did this but there wasn't a hint of tech specs on them or any way to purchase them; Worse yet I can't seem to find them again to share here.

So, over the next couple of weeks I will be working on a new intercom utilizing the video capabilities in asterisk console using chan_oss instead of alsa. I don't have any experience with oss but here we go.

Also, now that I actually have people following this project, I'm going to work to improve my documentation.
