[Asterisk-Users] Asterisk and LCR

[Johann]

My company is thinking about putting most of the logic for determining 
which route is the cheapest in an AGI script.  Some dialplan logic 
wrapped around it to attempt to dial the routes in the order returned.  
It hasn't been fully implemented yet.

The idea is to move the routing decision making outside of asterisk so a 
programming language can be taken advantage of without relying on always 
changing the extensions.conf file.
