[asterisk-users] multiple asterisk approach

Use DUNDi, perfect for this.  The protocol is very light, no load on
the servers to run it, can handle hundreds of queries a second with no
load.  You want to use regcontext and a few other things to make it
all work together.  Here are some papers to guide you:

Good Luck.
