Even the subject is clearly of topic... sorry about that :) We are in the process of changing our billing system. As far as I can tell most vendors of "billingware" (such sage highdeal etc...), et least the one we have met, now prefer using diameter interfaces over radius. It seems even more true when it comes to telco specialists. Unfortunately a lot of our network devices do not supports diameter right now (untill we change them). Does networkradius, also have experience in deploying diameter? Does the free implementation of diameter are reliable or proven (may be you have your own)? And at least is it possible to build some kind of gateway between radius and diameter? Bests regards. -- <http://www.horoa.net> Alexandre Chapellon Ingénierie des systèmes open sources et réseaux.
