[Asterisk-Users] Polling Asterisk for Life

The _only_ way to reliably (well, in as much as that is possible) to 
test if your Asterisk is working, is to build a monitoring system that 
does more or less the same as a typical user would do.

We have a system with two modems connected to ATA's and they dial each 
other via multiple routes so we test all of the major scenarios. 

We only test if calls are routed through, not if the call itself 
establishes (media running) to prevent major costs from such a 
system. I works reasonably well, it seems to detect 99% of the major 
problems.
