If Worldcom and UUNet jumped off a bridge would you?

I have been over and over and over this...  RADIUS adds another layer of 
failure to your network, lots of overhead, and unnecessary complication.

Think VHS and Beta...  Beta is a superior technology but VHS was 
successfully marketed.   Since RADIUS seemed to work for dial up 'they' 
assumed it is natural for VoIP, well they are very wrong.  

Try doing pre-paid calling cards with Cisco's RADIUS implementation... I 
dare you.  

Why in hell do you think everyone is always looking for a billing 
system?  I have personally talked to dozens of ppl that have spent major 
money on SysMaster (and the like) and they absolutely hate it.  Why?  
because it is a kludge... It is dramaticly overcomplicated and at the 
end of the day it doesn't really do what they need.

CDR backend, Rating Engine and MySQL. 

I've personally chosen not to share my billing system. First off, my 
billing code will never see the light of day, so that means a non-gpl 
license you would have to get from Digium and at this point my operation 
is not far enough along to support both termination customers and 
customers running our billing system.
