I'm sure I will encounter it in the book, but I'm looking to  
understand what actually needs to occur.

Basically their scenario is a small auditorium that is already  
connected to the existing phone line so that ones may listen in over  
the 3-way to 3-way to 3-way (ad infinitum) chain.  They have a *very*  
simple setup.  There is no internet or internal network.

That said, is there any way technologically to branch/bridge a normal  
phone line using Asterisk (or anything else), or must I have some  
other number/service coming in?

Also, I believe there was a bit of confusion with an earlier post.   
Although they wish to *host* the entire setup in-house, they will have  
external callers.

I'm certainly not opposed to the various proposed solutions, but given  
the nature of the project you can understand that I don't want to  
spend resources on items they don't absolutely need.

Best,

Michael
