Re: least cost rounting and failed calls.

i think the interesting part about call re-routing is that it will have to be 
taken in small steps.  from my experience when gnugk tries to set up a call 
with a remote GW if the GW sends back an ISDN message like release complete 
before alerting or no circuit/no channel i can imagine that gnugk could 
re-process this call to another provider with only small delays. i think the 
larger problem is going to be to determine what additional conditions require 
re-routing and how to granulate and specify them. i dont imagine that even 
the radius routing would be able to handle this unless if gnugk would send a 
second setup request to radius and then radius then sends a second route that 
is to be considered. this would pass the responsibility to re-route the call 
from the gnugk to the radius implementation. since there is call id 
information then it would be up to radius client to identify that it already 
sent a route and it failed via a second request and either provide another 
route or just send a reject message back.

in the adventure to develop re-routing then we will see the transformation of 
the gnugk to be then a softswitch.

i have participated in the project for about a year now and i  have seen great 
and very important changes and i am proud to have been witness to it, great 
job michal..

regards
ray
