I've really appreciated all the posts here and we have used many of the ideas over the past 3 months as we have implemented this. We are using a Slingbox to stream the video.
From the suggestions of others on this forum, we want to have an audio backup ready over a regular phone line -- just in case the video streaming runs into problems. I know how to receive phone audio using the crab-box to bridge between the phone line and sound system. I don’t know a simple way to send the audio over a phone line other than the obvious – using a muted speaker phone. Does anyone have a simple approach for an “off the shelf” or easy to build way to take a line level or mic level signal and “insert” that signal into a phone?

I believe the EJ-10 is only one-way: phone line to audio system. I don't think you can go the other way.
We used a true telephone hybrid. See: http://www.bswusa.com/proditem.asp?item=TT1
Great audio, powered off the phone line. If you want to go cheap, bug one of the hams in your stake who's got one to use their hybrid phone patch. It's a bit of a messy setup, but it works.
