Right, the TDMoE virtual zaptel configuration as pointed out by Colin 
Anderson's post.

But I also saw the note about 2.6+ kernel issues, so I threw my idea at 
you. As far as dialing in to Server A's extensions, either plan them so 
they don't conflict, or prepend a digit to push calls into the right 
context on Server A when coming out of Server B.
